ON TIME DELAY
0.0 to 3275.0 seconds
Enter the time value in seconds that the alarm is delayed from turning on after
the trigger point is reached. A value of 0.0 allows the meter to update the alarm
status per the response time listed in the Specifications. When the output logic
is rEv, this becomes off time delay. Any time accumulated at power-off resets
during power-up.
OFF TIME DELAY
0.0 to 3275.0 seconds
Enter the time value in seconds that the alarm is delayed from turning off after
the trigger point is reached. A value of 0.0 allows the meter to update the alarm
status per the response time listed in the Specifications. When the output logic
is rEv, this becomes on time delay. Any time accumulated at power-off resets
during power-up.
OUTPUT LOGIC
nor rEv
Enter the output logic of the alarm output. The nor logic leaves the output
operation as normal. The rEv logic reverses the output logic. In rEv, the alarm
states in the Setpoint Alarm Figures are reversed.
RESET ACTION
Auto LAtCh1s LAtCh2
Enter the reset action of the alarm output.
Auto = Automatic action; This action allows the alarm output to automatically
reset at the trigger points per the Setpoint Action shown in Setpoint Alarm
Figures. The “on” alarm may be manually reset immediately by a front panel
function key or user input.The alarm remains reset until the trigger point is
crossed again.
LAtCh1 = Latch with immediate reset action; This selection latches the alarm
output on at the trigger point per the Setpoint Action shown in Setpoint Alarm
Figures. Latch means that the alarm output can only be turned off by front
panel function key or user input manual reset, serial reset command or meter
power cycle. When the user input or function key is activated (momentary or
maintained), the corresponding “on” alarm output is reset immediately and
remains off until the trigger point is crossed again. (Previously latched alarms
will be off if power up Display Value is lower than setpoint value.)
LAtCh2 = Latch with delay reset action; This selection latches the alarm output
on at the trigger point per the Setpoint Action shown in Setpoint Alarm
Figures. Latch means that the alarm output can only be turned off by front
panel function key or user input manual reset, serial reset command or meter
power cycle. When the user input or function key is activated (momentary or
maintained), the meter delays the reset event until the corresponding “on”
alarm output crosses the trigger off point. (Previously latched alarms are off
if power up Display Value is lower than setpoint value. During a power cycle,
the meter erases a previous Latch 2 reset if it is not activated at power up.)
SETPOINT STANDBY OPERATION
NO YES
When YES, the alarm is disabled (at power up) until the trigger point is
crossed.
