External Input Signals
The PS-A’s RAS interface connector uses the following input signals.
•
General-Purpose Input (DIN 2 bits)
This standard digital input is used for error/alert detection in external devices. The input signal uses two bits.
The System Monitor property of the control panel or the API-DLL can be used to enable or disable this
feature, as well as designate what type of processing is to be performed once a signal is received. (Only
the “ON” state of the DIN circuit is detected. The “OFF” state of the DIN circuit cannot be monitored.)
•
Remote Reset Input
This is the reset signal sent from an external device to the PS-A. When this signal is enabled, a forced
reset of the PS-A is performed.
The System Monitor property of the control panel or the API-DLL can be used to enable or disable this
feature.
•
To enable Remote Reset Input, make sure to check the [Enable] in the Remote reset tab of
System Monitor Property. For Remote reset of System Monitor Property, refer to the following.
