• Dedband (Hysteresis)
Once a high trip alarm is ON, the alarm stays ON until the data becomes lower than the deadband value from the setpoint.
Once a low trip alarm is ON, the alarm stays ON until the data becomes higher than the deadband value from the setpoint.
• One-shot output
Alarm outputs are provided as one-shot pulses. One-shot pulse is output when all parameters (input signal level, deadband,
ON delay time elapsed) of the setpoint become true.
Set 0.0 to provide normal contact outputs. One-shot output setting prevails OFF delay time.
If the display is set to flash in alarm, it starts flashing when the alarm output turns on, and stops flashing (ON) when it is
off.
In the event trigger modes other than ‘Normal,’ the one-shot output is provided if the parameters are all true at the timing
of measuring.
