1 Overview of the product

1-1 Features of this product

▪ The Uninterruptible Power Supply (UPS) protects such devices as PLC and IPC* from power

failures, voltage variations, and instantaneous voltage drops.

▪ Under normal conditions, the UPS outputs DC24V of electrical power from the DC power supply

as-is. When an abnormality is detected in the DC24V power supply such as a power failure and voltage variation, the UPS switches to battery supply to continue to provide DC24V of electrical power.

▪ For the specifications of PLC and IPC for power supply input and operation in the event of

momentary power interruptions, check the respective manuals. *IPC: Industrial PC (Industrial use computer)

For cautions when maintaining the UPS, refer to “Caution (for maintenance)” shown in the “Safety precautions” of the beginning of this manual.

5-1 Checking the battery

The battery used in the unit has a limited lifespan. (The life varies depending on your storage/use environment and backup frequency.)

The nearer the end of the life is, the more rapidly deterioration proceeds.

5-1-2 Self-diagnosis test

This test performs a failure diagnosis on the unit and performs a test to check for battery deterioration. Use the procedure below to check whether a circuit failure has occurred inside the unit and whether battery replacement is required.

There are two, automatic testing and manual testing, in the self-diagnosis test as follows.

■ Automatic testing

The self-diagnosis test is automatically performed at the factory settings, at the following timing in the state that the UPS is connected to a commercial power source and the charge of the battery has been completed. User’s operation to start the test is unnecessary.

▪ When the UPS is started up by pressing the “Power” switch ▪ When power has been supplied for four weeks

If the battery is not sufficiently charged, the self-diagnostic test is not performed. The test is automatically performed when the battery is charged completely.

5-1-3 Estimated backup time

The backup time varies depending on the capacity of connected devices. After calculating the total capacity of connected devices, refer to the graph of the backup time to obtain an estimation of the initial value of the backup time. (This is also applied to checking the battery.)

1. Convert the total capacity (power consumption) of the connected devices to watts (W).

The indicator can show values in two different ways: amperes (A), and watts (W).

Example 1: DC24V, 145W Example 2: DC24V, 1.8A

For devices that use the A indication, convert the capacity

into W.

Example : 1.8 (A) = 1.8 × 24 (W) = 43.2 (W)

Indication Value

2. Add the values converted into W to obtain the total capacity of the connected devices.

You can develop your unique system based on the following specifications to automate the process at a power failure. You can perform power-failure processing by allowing the system to detect the backup signal (BU) and also perform system shutdown processing by allowing the system to detect the low battery level signal (BL). Also, by inputting the backup stop signal (BS) from the system, you can stop the UPS with a sufficient battery level to prepare for the next occurrence of a power failure.

7-1-1 Type of output signals

The UPS has 4 kinds of output signals.

The output circuit consists of an open collector circuit using a photo coupler.

Low battery level signal output (BL) Goes ON when the battery becomes weak during backup operation

Trouble signal output (TR ) Goes ON when an internal failure of the UPS occurs or when the

Battery replacement signal output (W B) Goes ON when the test determines that battery replacement is

7-1-2 Type of input signals

The UPS has 2 kinds of input signals.

*BS signal delay time

It is possible to set the period of time from when a BS signal is received until the output of the UPS is stopped. The output of the UPS can be stopped by inputting the voltage signal (High).

using either an externally connected contact or the ON/OFF status of the open collector circuit. When signal is OFF, the UPS will be turned on. When signal is ON, the UPS will be turned off. In the factory settings, short-circuited. In addition, it is necessary to turn on the “Power” switch of UPS to

The computer stops when a power failure occurs.

Backup is performed too frequently. Frequent switching is performed although a power failure does not occur. You hear the sound of

Make sure the AC input is securely connected to commercial power. If the status indicator does not display properly after you perform the above operation, there is a problem with the unit. See “4-3 Interpreting beeps and displays”.

Perform the test after charging the battery for at least 4hours. The battery can be charged just by connecting the AC input to a wall outlet. The “Power” switch can be either ON or OFF. When input power supply is connected to the unit and the power is turned ON, battery charging operation starts.

Variations (decrease) in the input power occur frequently. Or, noise may be included that significantly distorts the voltage waveform of the input power. ▪Try and check what happens when connecting the unit to a different wall outl et (commercial

power) located som e distance away from the device consuming a large amount of power.
