The contact capacity is as follows:
Resistance load: 30 VDC, 2 A
The minimum allowable load is as follows:

A, 10 mV
To connect an inductive load, be sure to use a
surge absorber.
CAUTION
To output the Oil Cooling Unit operation status signal to the main machine, connect the required signal cable to the signal
terminal block according to the procedure below. For details of alarms, refer to “Alarm list” (page ). For details of warnings,
refer to “Warning list” (page ).
To use an output contact, change the parameter setting, and make sure that the output contact normally operates.
(For parameter setting changing procedure, refer to page .)
External output circuit
Alarm and warning output logic
The alarm and warning output logic can be changed
depending on the parameter setting. (See page .)
When the power supply is turned ON,
external output becomes unstable.
Set up the main machine sequence program so that the external
output signal is ignored for one second after power-ON.
