YORK, A Johnson Controls Company
2QF_#2
This group defines supervision for up to three signals from Group 01, Operating Data. Supervision
monitors a specified parameter and energizes a relay output if the parameter passes a defined limit.
Use Group 14, Relay Outputs, to define the relay and whether the relay activates when the signal is too
low or too high.

Selects the first supervised parameter.
• Must be a parameter number from Group 01 Operating Data.
• If the supervised parameter passes a limit, a relay output is energized.
• The supervision limits are defined in this group.
• The relay outputs are defined in Group 14 Relay Outputs (definition also specifies which supervision limit is
monitored).

HI represents a normal hysteresis.
"& ! *
Operating data supervision using relay outputs, when
LO>HI.
The lowest limit (
HI
3203) is active initially, and remains
active until the supervised parameter goes above the
highest limit (
LO
3202), making that limit the active limit.
That limit remains active until the supervised parameter
goes below the lowest limit (
HI
3203), making that limit
active.

whenever the supervised parameter goes above the
