VI.PLC interface
There is remote control connection terminal on the back plate of the tester. This terminal
can connect to remote manipulator to operate. It is a standard 9PIN D type terminal, with
the following signals: connection test signals, reset signal, signal under testing, test pass
signal, test fail signal.
1.Input signal & Output signal of PLC
2.Connection
TEST control: The control switch is connected between PIN 1 and PIN 3.
RESET control: The control switch is connected between PIN 1 and PIN 4.
Signal output under testing: Between PIN 2 and PIN 5.
Test fail signal: Between PIN 6 and PIN 7.
Test pass signal: Between PIN 8 and PIN 9.
3. Explain the Input & Output Signal Connection
This tester equips with remote control joints, and the TEST and RESET function of this
instrument can be manipulated by the outside remote control device. These joints provide
the power supply that holds control function, and thus the “Momentary Contact” switch
must be used to act as the controller. Important: These joints must be prohibited to
connect to any other power supplies. If they connect to other power supply, the inside
circuit of this instrument may be damaged.
The output signal provides contact of a relay.
