How do I customize alarm action within Commander when using with Watlow 981-984 Controllers?

Watlow Series 981-984

 

Uses Commanders Watlow 982 Modbus Table.

Commander does not support the method that Watlow uses for storing the ramp/dwell profile setpoints and therefore does not have the capability to display, change or view these values.

 

Watlow provides a Low and a High Alarm for each Alarm. Commander is setup to annunciate both conditions as standard. You can also edit the Commander Modbus Table to annunciate just the High or the Low alarm condition if desired.

 

From the Main Screen Menus:

Click Setup

Click Edit Modbus Tables

Select the Watlow 982 Table

Enter a value of “Decimal Places” for Alarm 1 Status and/or Alarm2 Status as below:

17 to annunciate both High & Low Alarms
13 to annunciate only High Alarms

14 to annunciate only Low Alarms

Commander has no provisions to signal open thermocouple conditions with this model.
