AlARM CONFIGURATION AND RElAy TEST
The alarm configuration and relay test operation cycles through different
stages as follows:
a. Set thresholds for A1, A2, A3, STEL, LTEL.
These stages are used to set the A1, A2, A3, STEL and LTEL alarm
threshold points and do not affect the alarm LEDs and relays.
b. Test lamps and optional relays for A1, A2, A3, Fault, STEL, LTEL.
These stages provide a lamp test and relay test function.
Note: When not configured for STEL/LTEL threshold, a row of dashes will
be displayed instead of a level and the STEL and LTEL faclilities
will be set permanently to off.
