Assigning Temperature Alarms

Once RTDs have been assigned to the circuit high and low temperature alarms may be set. The
alarm button will only appear if a RTD has been assigned to the circuit.

Fig. 3.10

Setup|Alarms window (HWAT)

HIGH LINE TEMP ALARM:

If any RTDs assigned to a circuit measures a temperature above this threshold, the ACS-UIT2
generates an alarm. The limit can be set for any temperature value you desire for your application
within the range allowed.

Range:

Maintain setpoint plus 10°F (6°C) to 190ºF (88ºC)

Default:

190°F (88°C)

LOW LINE TEMP ALARM:

If any RTDs assigned to a circuit measures a temperature below this threshold, the ACS-UIT2
generates an alarm.

Range:

40ºF (4ºC) to Maintain temperature

Default:

40°F (4°C)

TEMPERATURE ALARM FILTER:

This minimizes nuisance alarms by forcing the ACS-UIT2 to verify that the alarm condition
continually exists over the selected period of time before alarming.

Range:

0–999 minutes

Default:

15 minutes

Note:

Setting the Alarm Filter to 0 minutes is mainly for testing and demonstration purposes.

Choosing this option for normal use may cause nuisance alarming since this option may not allow
the ACS-UIT2 time to verify that the alarm conditions exist.

HIGH LINE TEMP CUT-OUT:

If any RTDs assigned to a circuit measures a temperature above this threshold, the ACS-UIT2
generates an alarm and the relay output is turned off. If the high line temperature drops below this
threshold minus the deadband, the output is turned on and normal duty cycle control is resumed.

Range:

High Temperature Alarm value plus 1°F (1°C) to 200ºF (93ºC)

Default:

200°F (93°C)
