Digital alarms
Digital alarms monitor the ON or OFF state of the meter’s
digital / status inputs.
Digital alarm with setpoint delay
To prevent false triggers from erratic signals, you can set up pickup and dropout time delays for the digital alarm.
|
|
|||
| A | Pickup setpoint (1 = ON) | ΔT2 | Dropout time delay (in seconds) |
| B | Dropout setpoint (0 = OFF) | EV2 | End of alarm condition |
| ΔT1 | Pickup time delay (in seconds) | ΔT3 | Alarm duration (in seconds) |
| EV1 | Start of alarm condition | ||
NOTE: To prevent filling the alarm log with nuisance alarm
trips, the digital alarm is automatically disabled if the digital
/ status input changes state more than 4 times in one second or more
than 10 times in ten seconds. In this case, you must re-enable the
alarm using the display or
ION Setup
