S8AS 11 maintenance forecast monitor function indication and output when the product is purchased, ? ful ? will be displayed. as the electrolytic capacitors deteriorate , the display will change to ? hlf ? (refer to maintenance forecast monitor function ). ? ful ? will be displayed for the maintenance forecast display for approximately one month after the power supply is first turned on. the accumulated value will then be displayed depending on the ambient conditions. (however, the ? hlf ? display may not appear, depending on the application environment and the set value for maintenance forecast.) if the maintenance forecast setting l (which can be set to 0.0 to 5.0 years in 0.5-year increm ents) is set to a value larger than two years, the display automatically changes to a value (l - 0.5) after the remaining time to maintenance is r educed to the set number of years, and an alarm (a23) and the remaining time will be displayed alternately. if the setting is less than 2.0 years, the display changes to a value (1.5) after the remaining time becomes less than two years, and after the remaining time becomes less than the set time, an alarm (a23) and the remaining time (l - 0. 5) will be displa yed alternately. if the alarm (a23) and a numeric va lue are displayed alternately, the transistor (maintenance forecast output terminal (yrs)) will turn off to indicate the need for maintenance., i.e., there will be no continuity at the maintenance forecast output terminals. (the lef output will turn off when the maintenance time has been reached.) example: display when the time remaining to the maintenance time is less than 0.5 yr note: 1. the time remaining to maintenance is based on continuous operation, not including the time when the power supply is turned off. 2. ? ful ? will be displayed until approximately one month of time has passed to enable estimating the speed of deterioration. the output will remain on (i.e., there will be continuity at the maintenance forecast output terminal (yrs)). 3. for details on the display, refer to relationship between displayed values and output of set values . maintenance forecast monitor function the power supply is equipped wi th electrolytic capacitors. the electrolyte inside the elec trolytic capacitors penetrates the sealing rubber and evaporates as time passes after it is manufactured. this causes deteriorat ion of characteristics, such as decreasing the capacitance. due to this deterioration of the ch aracteristics of the electrolytic capacitor, the power supply decr eases its performance as time passes. the maintenance forecast monitor function shows an approximate period left for maintenance of the power supply due to deterioration of electrolytic capacitors. when th e period left for maintenance that the power supply forecasts reache s the set value, an alarm is indicated and an output signal is tri ggered. use this function to know the approximate replacement timing of the power supply. note: the maintenance forecast monitor function indicates an approximate period left for maintenance, based on deterioration of the el ectrolytic capacitors. it does not predict failures resulting from other causes. relationship between displayed values and output of set values yrs a 5 4 3 2 16 v s c yrs a 5 4 3 2 16 v s c yrs a 5 4 3 2 16 v s c yrs a 5 4 3 2 16 v s c yrs a 5 4 3 2 16 v s c yrs a 5 4 3 2 16 v s c initial capacity (l ? 0.5) l: maintenance forecast set v al u e 0.0 to 5.0, 0.5 steps w hen l is set to b et w een 2.5 and 5 years. 5.0 maintenance forecast monitor o u tp u t l = 2.5 t: maintenance time u ntil replacement l = 0.5 the n u meric v al u e decreases w ith time. 2.5 2.0 1.5 1.0 0.5 0 main display electrolytic capacitor capacity capacity at replacement time "1.0" is displayed on the main display for the d u ration that the maintenance forecast u p to replacement satisfies the condition 1.0 t < 1.5.
12 S8AS principle of operation the deterioration speed of the el ectrolytic capac itors varies considerably with the ambient te mperature. (generally the speed follows the arrhenius law, i.e., for every 10 c increase in the temperature, the rate of degradat ion doubles.) the S8AS monitors the temperature inside the power supply, and calculates the amount of deterioration according to the operating hours and internal temperature. based on this amount of deteriorati on, the power suppl y will provide an alarm indication and output when the period left for maintenance reaches the set value. note: 1. due to degradation of internal electronic parts, replace the power supply approximately 15 years after purchase even if the maintenance forecast monitor indication and output do not appear. 2. the maintenance forecast is accelerated or decelerated according to operating condi tions. periodically check the display. 3. acceleration or deceleration of the maintenance forecast may cause the output to repeatedly go on and off. 4. the accuracy of the maintenance forecast function may be adversely affected by applications in which the ac input is frequently turned on and off. difference between expected life and replacement time omron calculates the expecte d life based on the following conditions. 1. rated input voltage 2. load rate: 50% 3. ambient temperature: 40 c 4. standard mounting note: the expected life is calculated by performing a temperature rise test using an aluminum electrol ytic capacitor, and therefore is not a guaranteed value. the expected life span of the S8AS is 10 years. the maintenance forecast is the service life (the power supply's internal temperature is monitored at all times) of the internal electrolytic capacitors in actual operating conditions, and depends on the customer's operating conditions. the maximum period of the maintenance forecast is taken as 15 years. other functions * the sequencing functions are designed for the six branch outputs of one S8AS. there is no synchronization processing between s8 as power supplies when more than one S8AS is used. sequencing functions for branch outputs 7 and 8 are available only with the S8AS-4800 8n. function operation startup sequence (refer to chart 5 .) the connection timing for branch outputs 1 to 6 and 8 can be se t individually to offset the connection timing to the load devices. creating time delays between starti ng loads enables safer load operation. it also reduces total inrush current so that power supply capacity can be optimized. setting range: 0.0 to 99.9 s in 0.1-s increments. for the S8AS-24006n and S8AS-48008n, the settings are 0.0 s for branch output 1, 0.4 s for branch output 2, 0.8 s for branch output 3, 1.2 s for branc h output 4, 1.6 s for branch output 5, 2.0 for branch output 6, 2.4 s for branch output 7, and 2.8 s for branch output 8. (cannot be changed.) * shutdown sequence (refer to chart 6 .) the cutoff timing for branch outputs 1 to 6 and 8 can be set indivi dually to offset the cutoff ti ming of load devices for the external tipping input or to enable an emergency stop. setting range: 0.0 to 99.0 s in 0.1-s increments. for t he S8AS-24006n and S8AS-48008n, all branch outputs have a setting of 0.0 s. (cannot be changed.) * startup delay a delay function is provided so that the abnormal current tripping function or overcurrent alarm function will not be triggered by large initial inrush currents, e.g., for capacitive loads or lamp loads. the abnormal current tripping function will function on ce the set time has elapsed.

be sure to remove the sheet covering the product during installation before turning on the power. installation environment ? do not use the product where it would be subjected to shock or vibration. a device such as a c ontact breaker may be a vibration source. set the product as far as possible from possi ble sources of shock or vibration. additionally , install a pfp-m end plate on each end of the product after mounting it to a din rail. ? if the product is used in an area with excessive electronic noise, be sure to separate the product as far as possible from the noise sources. ambient operating and storage environment ? store the product at an ambient temperature of ? 25 to 65 c and relative humidity of 25% to 90%. ? internal parts may occasionally be deteriorated or damaged. do not use the product in conditions exceeding the derating curve (in portion (1) of the derating curve on page 8). ? use the product where the relative humidity is 25% to 85%. ? do not use the product where it would be subjected to direct sunlight. ? do not use the product where it would be subjected to the possibility of penetration of liquid, foreign subs tance, or corrosive gas. ? to maintain performance of the maintenance forecast monitor, make sure the following conditions are satisfied for long-term storage. for storage exceeding three months, keep the product at a temperature of ? 20 c to 30 c and a humidity of 25% to 70%. output voltage adjustment ? the output voltage adjuster (v.adj.) may possibly become damaged. do not apply more than the required force. ? do not exceed the rated output capacity and rated total output current after adjusting the output voltage. periodic inspections under normal operating conditions, the product will require several years or even more than ten year s until the maintenance forecast monitor function operates. when using the product for an extended period of time, perform the followin g procedure periodica lly to confirm that the output for the maintenance forecast monitor function (lfe) is operating correctly. a) change to run mode. b) confirm that the (lfe) output is on (i.e., that there is electrical continuity between (lef) and (com)). precautions for correct use tripping performance ? when the tripping alarm output oper ates, always remove the cause of the output first and then reset the alarm. ? when using a load with a fixed- power operation, the S8AS may cause a cutoff when the power supply is turned off. ? outputs may be cut off by the abnormal voltage protection with loads that generate reverse peak electromotive force. ? tripping performance is depends on the ambient operating temperature. use the product within the derating range. refer to the derating curve on page 8. ? it is conceivable that internal parts may be deteriorated or damaged. do not repeatedly perform cutoff or recovery operations more than necessary. maintenance forecast monitor function the accuracy of the maintenance fo recast monitor function will be reduced in applications where the ac input turns on and off frequently. total peak output current the S8AS is designed to provide a te mporary peak current to provide the overcurrent required to start load devices. the total peak output current for all branch outputs combined is given below. however, if even one of the fo llowing conditions is not satisfied by the total current, all branch outputs will be cut off to ensure safety based on the amount of peak current and the usage time. ?

the S8AS is designed to withstand 3,000 vac for 1 minute between the ac input terminals collectively and the branch output, i/o signal, or communications term inals collectively. when testing, set the cutoff current for the withstand voltage test device to 20 ma. ? the S8AS may possibly be damaged from the impulse voltage if a testing device switch is used to abruptly apply or cut off 3000 vac. increase the applied voltage gr adually using the voltage adjustment on the testing device. ? when testing terminals together, always short the specified terminals so that the voltage is applied to all of the terminals at the same time.
S8AS 25 insulation resistance test ? when testing the insulation resistance, use a dc resistance meter at 500 vdc. ? to prevent damage, always short branch output terminals (+/ ? ), all i/o terminals, and communications terminals before testing. output voltage adjustment ? if the output voltage is set to less than 20 v (default setting), the undervoltage alarm may be activated. ? do not exceed the rated output capacity and rated total output current after adjusting the output voltage. ? the output voltage may increase beyond the allowable voltage range rated voltage +10% when the v.adj adjuster is used. when adjusting the output voltage, check the output voltage of the power supply to make sure that the load is not damaged. displaying the output voltage the voltage detection is performed on the voltage after ac/dc conversion in the interv al circuits. the displayed voltage will be somewhat different from the value at the output terminals of the power source due to internal voltage drop. to confirm correct output voltages, measure the voltages at the branch output terminals. no output voltage the internal circuit's overcurrent protection or overvoltage protection may operate. alternatively, the latc h protection circuit may operate if there is a lightning inrush or other large voltage applied to the input. contact your omron representative if there is still no output voltage after checking the following two points: ? checking overcurrent protection check whether the load is in an ov ercurrent or short-circuited state. remove the wires to the load before checking. ? checking overvoltage protec tion and latching protection turn the power supply off and leave it off for at least 3 minutes, then turn it on again. startup time at startup, the S8AS will che ck hardware and software before starting the operation of branch outputs. a time of approximately 3 seconds is required for these self-diagnostic functions. take this time into account when designing the system. external tripping input ? wire the polarity of the exte rnal tripping input correctly. ? after completing wiring, conf irm that operation is correct. tripping alarm output, undervoltage detection output, maintenance forecast monitor output, and over-temperature output photoswitch outputs: 30 vdc max., 50 ma max., residual voltage when on: 2 v max., leakage current when off: 0.1 ma max. ? wire all output signal circuits correctly. ? internal current control circuits ar e not provided internally for output signals. do not allow the output current to exceed 50 ma. ? after completing wiring, confirm t hat the circuits operate correctly. prohibition of parallel connection do not connect branch outputs from t he S8AS in parallel. also, do not connect the branch outputs in paralle l with branch outputs of other S8AS power supplies. connecting backup devices do not connect a battery or other backup power supply to the output of the product. harmonic current suppression circuit a harmonic current suppression circui t is built into the power supply. this circuit can create noise when th e input is turned on, but it will last only until the internal circuits stabilize and does not indicate any problem in the product. connections cannot b e made in parallel w ith other b ranch o u tp u t circ u its. s 8 as s 8 as s 8 as
