5.7 SERVICE REQUEST
5.7.1 Service Request (SRQ)
Service request is a message generated by the ZUP power supply to interrupt the controller. SRQ
can be generated by a power supply fault condition.
Each of the following conditions can generate SRQ message:
1. Over Voltage Protection (OVP).
2. Over Temperature Protection (OTP).
3. Foldback Protection.
The operator decides which of the conditions are defined as faults. Enabling or disabling a condition
from generating SRQ message does not affect the condition within the power supply.
5.7.2 Service Request message
The service request message consists of three characters terminated by EOS<CR><LF>.
The first character identifies the SRQ cause: 1-Foldback , 2-OVP , 3-OTP.
The 2’nd and 3’rd characters identify the ZUP power supply address.
Example: String generated by a ZUP unit :120<CR><LF> , means foldback protection was activated
