Note: 1. External noise is probable as a cause of "---", "e01", "e02" and "e03" errors. 2. Operation out of the derating curve area, ventilation error, and incorrect mounting direction are probable as a cause of "h%t" error. 3. If the "h%t" error state continues for about three hours, the maintenance forecast monitor function (S8VS-@@@24A only) becomes invalid. The indication for maintenance forecast monitor remains as "h%t" even after the overheat condition is removed, and the Yrs output (12) remains OFF (with no continuity across (12) and (13)). Replace the power supply if this condition occurs even if the output is correct, as internal parts may be deteriorated. 4. The "h%t" error detection function is only for the S8VS-@@@24A.

I Indication and Output
When the product is purchased, "ful" will be indicated. As electrolytic capacitors deteriorate, indication changes to "hlf". After the remaining time to maintenance is reduced to two years, indication automatically changes to a value, which decreases from "1.5" to "1.0" to "0.5" to "0" (year) as the running hours increase. If the maintenance forecast monitor setting is set to a value larger than two years, value indication automatically begins after the remaining time to maintenance is reduced to the set years. If the remaining time becomes smaller than setting L (which can be set arbitrarily between 0 and 5.0 years), an alarm (a02) and the remaining time are indicated alternately. With the S8VS-09024A, an output is given to an external device from a transistor ((12) Yrs) to notify of the replacement timing, together with indication. (The output is turned off after the replacement timing is reached; with no continuity across (12) and (13).)
In the case that the remaining time is reduced to smaller than 0.5 year and an alarm is issued.
I Multiple Alarms

Operation Mode
Undervoltage alarm * The indication shifts alternately in the direction of the arrow every 2 s.
Maintenance forecast monitor * * When undervoltage alarm is indicated: Press output load indication When the maintenance forecast monitor or overheat alarm is indicated: Press undervoltage alarm indication
Note: 1. The remaining time to maintenance is based on continuous operation, not including the time when the power supply is turned off, and so may take longer to reach than the actual time indicated. 2. Until the power supply has been turned for about one month in total, indication is fixed at "ful" to estimate the extent of deterioration, while the output remains turned on (with continuity across (12) and (13)).

Switch mode Power Supply S8VS
I Maintenance Forecast Monitor Function
The power supply unit is equipped with electrolytic capacitors. The electrolyte inside the electrolytic capacitor penetrates the sealing rubber and evaporates as time passes since it is manufactured, which causes deterioration of characteristics such as decreasing the capacitance, etc. Due to this deterioration of the characteristics of the electrolytic capacitor, the power supply unit decreases its performance as time passes. The maintenance forecast monitor function shows an approximate period left for maintenance of the power supply unit due to deterioration of electrolytic capacitors. When the period left for maintenance that the power supply forecasts reaches the set value, an alarm is indicated and an output signal is triggered. Use this function to know the approximate replacement timing of the power supply unit. Note: The maintenance forecast monitor function indicates an approximate period left for maintenance, based on deterioration of the electrolytic capacitor. It does not predict failures caused by other reasons.
Relationship Between Indicated Values and Output of Set Values
L: Maintenance forecast set value (See note.) 0.0 to 5.0, 0.5 steps Initial capacity (L-0.5) Capacity level at replacement "1.0" is displayed on the main display for the duration that the maintenance forecast up to replacement satisfies the condition 1.0 T < 1.5. In case of setting L between 2.5 and 5 years.

Note: This function can be set only on the S8VS-09024A Model.
The numerical value decreases with time.
I Principle of Operation
The deterioration speed of the electrolytic capacitor varies considerably according to the ambient temperature. (Generally the speed follows "Rule of Two for every 10C"; for every 10C increase in temperature the rate of degradation doubles according to Arrhenius's equation.) The S8VS-0@024A monitors the temperature inside the power supply, and calculates the amount of deterioration according to the running hours and inside temperature. Judging by this amount of deterioration, the power supply will give the 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 at least once every 15 years even if indication and output of maintenance forecast monitor are not issued. 2. The maintenance forecast is accelerated or decelerated according to operating conditions. Periodically check indication.
I Reference Value
Item Reliability (MTBF) Value Definition 135,000 hrs MTBF stands for Mean Time Between min. Failures, which is calculated according to the probability of accidental device failures, and indicates reliability of devices. Therefore, it does not necessarily represent a life of the product.
Life 10 yrs. min. The life expectancy indicates average opexpectancy erating hours under the ambient temperature of 40C and a load rate of 50%. Normally this is determined by the life expectancy of the built-in aluminum electrolytic capacitor. Note: The "maintenance forecast" is the service life (the power supply's internal temperature is monitored at all times) of the internal electrolytic capacitor in actual operating conditions, and varies according to the customer's operating conditions. 15 years is taken as the maximum period of the maintenance forecast.

The possible cause for no output voltage may be the presence of an overload or overvoltage condition, or may be due to the functioning of an latching protective device. The latching protection may operate if a large amount of surge voltage such as a lightening surge occurs while turning on the power supply. In case there is no output voltage, please check the following points before contacting us: Check the Overload Protected Status: * Check whether the load is in overload status or is short-circuited. Remove wires to load when checking. * Attempt to clear the overvoltage or latching protection function: Turn the power supply off once, and leave it off for at least 3 minutes. Then turn it on again to see if this clears the condition.

Power Supplies
I Overload Protection
50- to 300-W Models
The Power Supply is provided with an overload protection function that protects the load and the power supply from possible damage by overcurrent. The protection function operates when the load current rises above an overcurrent set value (105% of the rated load current). For a short-circuit or overcurrent lasting less than 20 seconds, output voltage is decreased to protect equipment. When the output current falls within the rated range, the overload protection function is automatically cleared.
Output voltage (V)
I Overvoltage Protection
The Power Supply is provided with an overvoltage protection function that protects the load and the Power Supply from possible damage by overvoltage. When the output voltage rises above a set value (115% of the rated output voltage), the protection function is triggered, shutting OFF the output voltage. If this occurs, reset the Power Supply by turning it OFF for 1 minute min. and then turning it ON again.

Note: Do not continue using the S8PS under short-circuited or overcurrent conditions for longer than 20 seconds, otherwise the internal elements of the S8PS may be damaged or broken.
I Overheat Protection Function
600-W Model Only
If the internal temperature of the S8PS rises excessively as a result of fan failure or any other reason, the overheat protection circuit will be triggered to protect the internal elements of the S8PS and simultaneously a protection-ON alarm indicator will be lit. To reset the S8PS turn OFF the input voltage, leave the S8PS for at least one minute and then apply the input voltage again.
600-W Models
If an excessive current flows for 5 s or more, the output will be turned OFF and simultaneously protection-ON alarm indicator will be lit. To reset the S8PS, turn OFF the input voltage, leave the S8PS for at least three minutes, and then apply the input voltage again. Note: Do not continue using the S8PS with the output terminals short-circuited or the overcurrent condition continued, otherwise the internal elements of the S8PS may be damaged or broken.

Precautions
!Caution
Be sure to connect the grounding line. Not doing so may result in electric shock.
Parallel Operation
Only 300- and 600-W models can be in parallel operation provided that they are operated under 90% of the ratings. Do not operate any other models in parallel. Make sure that the thickness and the length of all wires connected to the load are the same to ensure that the wires will have no voltage drop differences.
+V INPUT -V
!WARNING
Do not attempt to disassemble the Power Supply or touch its internal parts while power is being supplied. Doing so may result in electric shock. Do not touch the terminals of the Power Supply within one minute after power has been turned OFF. Doing so may result in electric shock due to a residual voltage. Do not touch the S8PS or heat radiation fin while the power is being supplied or immediately after the power is turned OFF. Otherwise, a skin burn may result from the hot Switching Power Supply or radiator.
+V
Mounting
To improve and maintain the reliability of the Power Supply over a long period of time, adequate consideration must be given to heat radiation. The Power Supply is designed to radiate heat by means of natural air-flow. Therefore, mount the Power Supply so that air flow takes place around the Power Supply. When mounting the Power Supply, mounting it to a metal plate is recommended. Forced air-cooling is highly recommended. It is recommended that the clearance around the Power Supply be larger than those shown on page page 71 under Standard Installation.
INPUT -V
Fan Replacement
The service life of the fan is approximately 50,000 hours (at 25C). The service life varies, however, depending on the ambient temperature or other surrounding environmental conditions such as dust. As a preventive maintenance measure, replace the fan within two years if it is used at an ambient temperature of 40C. Fans are available as replacements.
Generating Output Voltage ()
An output of can be generated by using two Power Supplies as shown below, because the Power Supply produces a floating output.
