•
If the Gap Full Scale Range option is in
engineering units instead of volts, this
section still applies with the exception that
the gap value will be referenced to zero
position at the center of the meter scale.
1. To test Gap alarms for Channel A, Press
the
GAP
switch and adjust the function
generator DC bias so that the Gap voltage
is within the gap alarm setpoint window
(See section
7
for viewing the gap Alert
setpoint window).
2. Press
the
RESET
switch and verify that
the
OK
LEDs are on, and the
ALERT
and
DANGER
LEDs are off.
3. Adjust the gap voltage on the monitor
to just exceed the Over Gap Alert
setpoint level and verify that the
ALERT
LED comes on after the 6
second delay period has elapsed
(flashing if the First Out option is
selected).
•
Verify that the Alert relay changed
state.
4. Press
the
RESET
switch on the system
monitor and verify that the
ALERT
