WARNING! Do not rely solely on the failed sensor alarm to ad-
just the output in the event of a sensor failure. If
the loop is in manual mode when a failed sensor
alarm occurs, the output is not adjusted. Install in-
dependent external safety devices to shut down
the system if a failure occurs.
Open Thermocouple Heat/Cool Output Average
If you set this parameter to on and a thermocouple open
alarm occurs, a loop set to automatic control mode will
switch to manual mode at the average output prior to the
alarm.
Values: on (1) or off (0). Values in parentheses are for seri-
al communications and LogicPro, and are stored as the sec-
ond (heat) or third bit (cool) of the value at this address.
Default: off (0)
Modbus Address (Loops 1 to 9): 44443 to 44451, second
bit (heat) or third bit (cool)
Parameter Number: 86
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 86.1 to 86.9, second bit
(heat) or third bit (cool)
Heat/Cool Output Curve
Choose an output curve. If curve 1 or 2 is selected, a PID
calculation results in a lower actual output level than the
linear output requires. Use curve 1 or 2 if the system has a
nonlinear response to the output device.
Values: linear (0), curve 1 (1) or curve 2 (2). Values in pa-
rentheses are for serial communications and LogicPro.
Default: linear (0)
Modbus Address (Loops 1 to 9): 44273 to 44281 (heat) or
44290 to 44298 (cool)
Parameter Number: 76 (heat) or 77 (cool)
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 76.1 to 76.9 (heat) or
77.1 to 77.9 (cool)
