Omega CN1166 manual Parameter Details, Parameter Function Adjustment Range Default Value

NOTES

1.Not operative if Proportional Band = 0.

2.Switching differential for ON/OFF control output.

3.Optional; only one legend will appear for each alarm.

4.Only applicable if a DC linear input is fitted.

5.Only applicable if Output 2 is fitted as a secondary control (COOL) output.

6.Applicable only if the Communications Option is fitted.

7.When a program is running, respective to program setpoint.

2.1PARAMETER DETAILS

Parameter	Function	Adjustment Range	Default
			value
Input Filter Time	Filter removes extraneous impulses	OFF, 0.5 to 100.0	2.0
Constant	from the process variable input	seconds in 0.5 second	seconds
		increments
Process Variable	Modifies actual process variable (PV)	￿input span of	0
Offset	value:	Controller
	Offset PV + actual PV
	= PV value used
Output Power 1	Current Output 1 power level	0 to 100%	Read only
Output Power 2	Current Output 2 power level	0 to 100%	Read only
Proportional	Portion of input span in which Output 1	0.0 to 999.9% of input	10.0%
Band 1 (PB1)	power level is proportional to the	span
	(offset) process variable value (see
	Figure 2-1).
Proportional	Portion of input span in which Output 2	0.0 to 999.9% of input	10.0%
Band 2 (PB2)	power level is proportional to the	span
	(offset) process variable value (see
	Figure 2-1).
Reset (Integral	Integral time constant	1sec. to 99min. 59	5 mins.
Time Constant)		secs. and OFF	00 secs.
Rate (Derivative	Derivative time constant	00 secs. to 99 mins.	1 min. 15
Time Constant)		59 secs.	secs.
Overlap/	Portion of proportional band (PB1 +	￿20% to +20% of	0%
Deadband	PB2) in which both outputs are active	(Proportional Band 1
	(overlap) or neither output is active	+ Proportional Band
	(deadband) - see Figure 2-1).	2)
Manual Reset	Bias applied to output power,	0% to 100% (Output 1	25%
(Bias)	expressed as a percentage of output	only);
	power.	￿100% to +100%
		(Output 1 & Output 2)
