NOTE 8: The PV HOLD alarm will turn on whenever the instrument is put into the PV HOLD mode. The
Alarm Setpoint Value for this alarm is the number of seconds before the alarm turns on after the PV
HOLD mode starts.
NOTE 9: The setpoint values for Healthwatch Timer Alarms are in Hours and fractions of an hour. For
example, a setpoint value of 20.10 would be for twenty hours and six minutes.
NOTE 10: When both alarm setpoints for a particular alarm are configured for the same Healthwatch
timer or counter, then the Setpoint 1 value turns on the alarm while the Setpoint 2 value turns off the
alarm and resets the timer or counter. For example:
If:
Alarm 1 Setpoint 1 (AL1 SP1) is configured for TIMER 2
Alarm 1 Setpoint 2 (AL1 SP2) is configured for TIMER 2
Alarm 1 Setpoint 1 Value (A1S1 VAL) is configured for 10.00 (ten hours)
Alarm 1 Setpoint 2 Value (A1S2 VAL) is configured for 11.00 (eleven hours)
Then:
When Timer 2 reaches 10.00 hours, Alarm 1 will turn on
When Timer 2 reaches 11.00 hours, Alarm 1 will turn off and Timer 2 will be reset to 0.00
NOTE 11: The setpoint value for PV Rate alarms is in Engineering Units (EU) per minute.

A1S1TYPE to actuate. The value depends upon
what the setpoint has been configured to represent.
No value is required for alarms configured for
Controller Mode, Communications Shed, Failsafe,
Thermocouple Warning, Thermocouple Fail or
