Manual Scanning
When used as a multipoint scanner this facility has been included mainly for commissioning
and fault finding purposes. It allows the system in the "RUN" mode to continually stay on
one point whilst checks are carried out. The normal scanning process is stopped.
When manual scan is in operation the system fault relay (Relay 4 on the Controller) will be in
alarm mode and the corresponding LED will be on.
Manual scan is enabled by programming Pr.53 = 1 and then re-entering "RUN" mode.
To select a specific point to be monitored press the relevant key 1-9 or 0, these correspond to
measuring points 1-10. To de-select manual scan set Pr.53 to 0 or power down then up
again.
NOTE:
1. When in manual scan, press "TEST" to display the gain value.
To return to normal display press the "CE" (Clear entry) key.
2. Module system status check does not operate during manual scan.
3. The unit will not automatically return to normal run mode. Reset Pr.53 to 0.
