Notification of the Refer to Chart 1. status is provided using the alarm display and the tripping alarm output (TRP). (See notes 2, 3 and 4.) The alarm display will alternate between the voltage and the alarm code (A10). The primary voltage is measured at the input terminals. Detection voltage: 28.8 V (fixed) Abnormal current tripping The output current is monitored and the branch output that is abnormal is cut off if the preset current is reached. Refer to Chart 2. Notification of the status is provided using the alarm display and the tripping alarm output (TRP). (See notes 2 and 3.) The alarm display will alternate between the current and the alarm code (A11). Abnormal current detection setting range: 0.5 to 4.0 A (S8M-CP04-RS: 0.5 to 0.38 A) in 0.1-A units. Either of two abnormal current tripping types can be set. Standard detection: Tripping within 100 ms. (If a current exceeding the set value flows for 80 ms or more, it is detected as an abnormal current and power is cut off within 20 ms.) Instantaneous detection: Tripping within 20 ms. (If a current exceeding the set value flows for 10 ms or more, it is detected as an abnormal current and power is cut off within 10 ms.) (Refer to page 14 for the setting procedure.) Tripping by external signal The output can be cut off by inputting a voltage to the external tripping input (TRG terminal). If a shutdown sequence (See note 2.) has been set, outputs will be cut off according to the shutdown sequence. (Refer to page 14 for information on the shutdown sequence.) External input signal width: 10 ms min. External tripping enable/disable setting: Enabled Input signal levels High level: 19.2 to 30 VDC Low level: 0 to 2.5 VDC Tripping can also be performed by using communications (S8M-CP04-R/RS only). Refer to the S8M User’s Manual (Cat. No. Z241) for information on tripping using communications. Note: 1. Two abnormal current tripping types are supported depending on the tripping current characteristics: Standard detection and instantaneous detection. Select the required tripping type. 2. Outputs are cut off using semiconductor relays and electrical insulation is not provided. 3. The output will remain OFF and the alarm display and alarm output will not be cleared even if power is restored. The S8M must be reset to restore operation. (Refer to List of Alarms on page 16 for details.) 4. The voltage at the power input terminals is monitored to detect abnormal voltages. To confirm correct output voltages, measure the voltages at the branch output terminals.

The alarm display will alternate between the voltage and the alarm (See notes 1 and 2.) code (A20). The primary voltage is measured at the input terminals. Overvoltage alarm setting range: 20.0 to 28.8 V in 0.1-V units. (Refer to page 14 for the setting procedure.) Overcurrent alarm Each branch output current is monitored and notification is provided using the alarm display and output (ALM) if (Refer to Chart 2.) the preset value is reached. (See note 1.) The alarm display will alternate between the current and the alarm code (A22). Overcurrent alarm setting range: 0.5 to 4.0 A (S8M-CP04-RS: 0.5 to 0.38 A) in 0.1-A units. Either of two tripping types can be set. Standard detection: An alarm is output if the current exceeds the set value for 80 ms or longer. Instantaneous detection: An alarm is output if the current exceeds the set value for 10 ms or longer. (Refer to page 14 for the setting procedure.) Undervoltage alarm The voltage is monitored and notification is provided using the alarm display and output (ALM) if the voltage drops (Refer to Chart 1.) below the preset voltage for more than 80 ms. The alarm display will alternate between the voltage and the alarm (See notes 1 and 2.) code (A21). The primary voltage is measured at the input terminals. Undervoltage alarm setting range: 18.0 to 26.4 V in 0.1-V units. (Refer to page 14 for the setting procedure.)

The alarm display will alternate between the run (See note 1.) time and the alarm code (A23). Display range: 0.0 to 99.9 kh in 0.1-kh units. Run time setting range: 0.0 to 99.9 kh in 0.1-kh units. (Refer to page 14 for the setting procedure.) Over-temperature output The internal temperature of the S8M is monitored using a built-in temperature sensor and notification is provided (Refer to Chart 4.) using the alarm display and over-temperature output (TMP) if the preset temperature is exceeded for more than (See note 1.) 1 s. The alarm display will alternate between the temperature and the alarm code (A30). The over-temperature output is convenient for control operations, such as operating a cooling fan to suppress temperature increased in the control panel. Note: The alarm display and over-temperature output are automatically cleared if the temperature falls below the set temperature. Display range: −10 to 100°C in 1°C units. Temperature setting range: 25 to 80°C in 1°C units. (Refer to page 14 for the setting procedure.) Note: 1. Branch outputs are not cut off for the alarm functions. 2. The voltage at the power input terminals is monitored to detect abnormal voltages. To confirm correct output voltages, measure the voltages at the branch output terminals.

Installation Environment The Product will be damaged. Do not incorrectly connect the polarity of power input terminals. Do not use the S8M in locations subject to shocks or vibrations. In particular, install the S8M as far away as possible from contactors or other devices that are vibration sources. Additionally, install a PFP-M End Plate on each end of the S8M. ■ Precautions for Safe Use Install the S8M well away from any sources of strong, high frequency noise and surge. Mounting Operating Life Take adequate measures to ensure proper heat dissipation to increase the long-term reliability of the S8M. Install the S8M so that The life of the S8M is determined by the life of the electrolytic the air flow circulates around it, because the S8M is designed to capacitors used inside. Here, Arrhenius Law applies, i.e., the life will radiate heat by means of natural air flow. be halved for each rise of 10°C or the life will be doubled for each Improper mounting will interfere with heat dissipation and may drop of 10°C.

The switch Ambient Operating and Storage mode power supply connected to inputs and any other sources of heat, however, must be separated as shown below. Environment Store the S8M at a temperature of −25 to 65°C and a humidity of (See note 1.) (See note 2.) 25% to 90%. Internal parts may occasionally be deteriorated or damaged. Do not use the S8M in areas outside the derating curve (i.e., in the area shown by shading ( ) in the derating curve diagram on page 6). Surrounding air temperature for UL 508 Listing and UL60950-1 Recognition is 50°C. Use the S8M at a humidity of 25% to 85%. (See note 3.) (See note 1.) Do not use the S8M in locations subject to direct sunlight. (See note 4.) Do not use the S8M in locations where liquid, foreign matter, or corrosive gases may enter the S8M. Note: 1.

The S8M may possibly be damaged from the impulse voltage if a testing device switch is used to abruptly apply or shut off 500 VAC. Increase the applied voltage gradually using the voltage adjustment on the testing device. Always short the specified terminals so that the voltage is applied to all of the terminals at the same time. Power input terminals and branch output terminals are not isolated. Do not perform dielectric strength tests or other insulation appraisal testing between inputs and outputs. External Tripping Input When using the external tripping input, always confirm the application methods described in the S8M User's Manual (Cat. No. Z241) before designing the system. Display The voltage detection function monitors the voltage at the power input terminals. Measure the voltage at the branch output terminals to confirm that the output voltage is correct. Backup Device Connections Observe the following precautions when using a backup device, such as one from OMRON's S8T Series. When connecting a backup device to an S8M branch output, the backup current will be supplied to other branches through internal circuits and it is conceivable that internal parts may be deteriorated or damaged at the same time. When using a backup device with the S8M, connect the backup device to the power input side. When connecting a backup device to the S8M input side, the backup time will be shorter than normal due to internal power consumption. Always confirm the backup time when using a backup device. 21 S8M Troubleshooting If the S8M is not operating properly, check the items listed in the following table before requesting repairs.
