Description
Modes d, r, b: relay cut-off point
Mode I: primary setpoint
Difference relative to setpoint or offset at which the
load is switched On or Off
Modes d, r: difference between setpoint and Stage 2
Mode b: deadband (centered on setpoint)
Mode I: secondary setpoint
Lower limit of end-user setpoint adjustment
Upper limit of end-user setpoint adjustment
Time delay between equipment On cycles for direct
stages
Time delay between equipment On cycles for reverse
stages
Rate at which condition approaches setpoint
High condition alarm On, value relative to setpoint
Low condition alarm On, value relative to setpoint
Condition difference relative to high and low alarms at
which alarm output is switched Off
Delay between alarm detection and activation
Compensates for long sensor leads or sensor location
Adjusted condition value when sensor input is 0.0 VDC
Adjusted condition value when sensor input is 10.0 VDC
Time delay between display refreshes
Configuration for normally closed binary input
Value of setpoint shift when binary input is open and
IF=2
Time between binary input detection and enabling of IF
Minimum amount of time between two successive
stages
