When a module is configured as non-redundant and uses a redundant IOTA, ensure that the lower slot is kept empty or if a module is plugged into the bottom slot, make sure that the module MUST be powered off.

inputs units
SETPOINT LOW LIMIT* — this selection prevents the
local and remote setpoints from going below the value
selected here. The setting must be equal to or greater
than the lower range of input 1 and input 2. Input 2,
when configured for remote setpoint, will be restricted to
this lower limit.
ACTION CONTROL OUTPUT DIRECTION — in what direction
do you want the recorder output to go when the process
variable increases.
DIRECT DIRECT ACTING CONTROL — the recorder's output
increases as the process variable increases.
REVRSE REVERSE ACTING CONTROL — the recorder's output
decreases as the process variable increases.
OUTHILIM –5.0 to 105.0% of output HIGH OUTPUT LIMIT — this is the highest value of
output beyond which you do not want the recorder
automatic output to exceed. Use 0 to 100% for time
proportional output type.
OUTLOLIM –5.0 to 105.0% of output LOW OUTPUT LIMIT — this is the lowest value of
output below which you do not want the recorder
automatic output to exceed. Use 0 to 100% for time
proportional output type.
DROPOFF –5 to 105.0% of output CONTROLLER DROPOFF VALUE — select an output
value that below which the recorder output will dropoff to
the low output limit value set in prompt "OUT LOLIM."
DEADBAND
–5.0 to 25.0%
0 to 25.0%
0.5 to 5.0%
DEADBAND is an adjustable gap between the
operating ranges of output 1 and output 2 in which
neither output operates (positive value) or both outputs
operate (negative value). It is the difference between the
nominal trip points of relay 1 and relay 2.
Time Duplex
On-Off Duplex
Position Proportional
OUT HYST 0.0 to 5.0% of PV span HYSTERESIS (OUTPUT RELAY ONLY) is an
adjustable overlap of the ON/OFF states of each control
output. This is the difference between the value of the
process variable at which the control outputs energize
and the value at which they de-energize. Only
applicable for ON-OFF control.
FAILSAFE 0 to 100% FAILSAFE OUTPUT VALUE — the output level used
when you have communications SHED or when NO
BURNOUT is configured and input 1 fails.
