Basic Features ｜ Protection functions and Alarms
Communication monitoring (WATCHDOG)
The watchdog function monitors the SCPI command communication status.
Communication is assumed to have stopped if there is no communication within the time
period specified by the communication monitoring timer setting (CF21).
The function operates regardless of whether the product is in remote or local (panel control)
mode. If you are not using remote control (commands), set communication monitoring off
using a timer setting.
In the alarm state, turn off communication monitoring before clearing the alarm.
Shutdown (SD)
The shutdown function allows you to turn off the output by applying a signal to pin 16 of the J1
connector when an abnormal condition occurs (p.96).
To release the shutdown (SD) function, turn the POWER switch off and then back on.
Master-slave parallel operation protection (PRL ALM)
If a slave unit stops due to an error during master-slave parallel operation, the master unit
detects the alarm and shuts down the output of the entire system.
This function protects devices by preventing the master unit and the remaining slave units
from continuing the output.
Connect pin 14 of the J1 connectors of the master unit and slave units.
To release PRL ALM, turn the POWER switch off and then back on.
