Rear Pins Module
Hysteresis or Deviation
Each setpoint can be individually
programmed to energize the relay in
the hysteresis or deviation mode,
with or without initial startup inhibit.
Hysteresis
(deadband) is the pro-
grammable band above and below
the setpoint value that determines
when and for how long the relay is
energized or de-energized. The set-
point can be programmed to ener-
gize the relay above or below the
setpoint value.

Relay Energize Functions
All setpoints activate at the setpoint value.
All relays/setpoints are programmable to
energize above or below the setpoint
value.

channel, selected meter register, or
external switched inputs (digital input
pins).

Data Logging
Any setpoint can be programmed
to log data within the meter (up to
4000 samples).
Data Printing to Serial Printer
Any setpoint can be programmed
to send data directly to a serial
printer.
Data Printing to PC
Any setpoint can be programmed
to send data directly to a con-
nected PC.

Hysteresis or Deviation
Each relay can operate in a hys-
teresis or deviation mode.
Timer Modes
Each setpoint can be programmed to
operate the relay in one of the follow-
ing seven resident timer modes:

SETPOINT TRACKING
Display Flashing
Display flashing can be applied to setpoints configured in the
hysteresis or deviation modes.
Each setpoint can be programmed to make the display flash on
and off while the setpoint is active, and keep it flashing until the
setpoint de-activates.
Setpoint Tracking
Setpoint tracking can be
applied to setpoints
configured in the hys-
teresis, deviation, or
PID modes.

tions. PID control is available from the following outputs:
•
Setpoint / relay output.
•
Analog output.
•
Relay and analog output at the same time.
PID control from the setpoint / relay output is available from
SP1 and SP2 only.
There are two PID control outputs available via the analog output:
•
PID1
–
stored in register 50.
•
PID2
–
stored in register 51.

The hysteresis setting can be any value between 0 and 65535
counts. The number of counts selected act both positively and
negatively on the setpoint, forming a hysteresis band around
the setpoint.
For example, if the setpoint setting is 500 counts and the hys-
teresis setting is 10 counts, the hysteresis band around the
setpoint setting is 20 counts, starting at 490 counts and ending
at 510 counts.
Note:
If hysteresis is set with ZERO counts, the relay energizes
AT or ABOVE the setpoint value.
