ALARM
01 SDAC HI VALUE?
10.00 VDC
Selectable values:
0.10
to
10.00 VDC
or
0.10
to
20.00 MA
. This value must be greater than
the
SDAC LO VALUE
.
Heat or Cool Output Action
Select the control action for the output. Normally, heat outputs are set to reverse action and cool
outputs are set to direct action. When output action is set to
REVERSE
, the output goes up when
the process variable goes down. When set to
DIRECT
, the output goes up when the process
variable goes up.
ALARM
01 HEAT OUTPUT
ACTION? REVERSE
Selectable values:
REVERSE
or
DIRECT
.
Heat or Cool Output Limit
This parameter limits the maximum PID control output for a loop’s heat or cool output. This limit
may be continuous, or it or it may be in effect for a specified number of seconds (see the next
parameter). If you choose a timed limit, the output limit time restarts when the controller powers up
and whenever the loop goes from manual to automatic control. The output limit only affects loops
under automatic control. It does not affect loops under manual control.
ALARM
01 HEAT OUTPUT
ACTION? REVERSE
Selectable values:
0
to
100
%.
Heat or Cool Output Limit Time
Set a time limit for the output limit set at the previous parameter.
ALARM
01 HEAT OUTPUT
LIMIT TIME? CONT
Selectable values:
1
to
999
seconds, or to
CONT
(continuous).
