0 Energizes ABOVE setpoint value
HYSTERESIS selected –
relay energizes AT OR ABOVE setpoint value plus hystere-
sis counts. De-energizes BELOW setpoint value minus hysteresis counts.
Note:
If hysteresis set with ZERO counts, relay energizes AT OR ABOVE the setpoint value.
DEVIATION selected –
relay energizes INSIDE deviation band (setpoint ± deviation
counts). De-energizes OUTSIDE deviation band (setpoint ± deviation counts).
PID selected –
controls ABOVE setpoint value.
1 Energizes BELOW setpoint value
HYSTERESIS selected –
relay energizes BELOW setpoint value minus hysteresis
counts. De-energizes AT OR ABOVE setpoint value plus hysteresis counts.
Note:
If hysteresis set with ZERO counts, relay energizes BELOW the setpoint value.
DEVIATION selected –
relay energized OUTSIDE deviation band (setpoint ± deviation
counts). De-energized INSIDE deviation band (setpoint ± deviation counts).
PID selected –
controls BELOW setpoint value.
2 Energizes AT OR ABOVE setpoint value with FALLING INPUT SIGNAL INITIAL
START-UP INHIBIT
HYSTERESIS selected –
relay energizes AT OR ABOVE setpoint value plus hystere-
sis counts with FALLING INPUT SIGNAL INITIAL START-UP INHIBIT. De-energizes
BELOW setpoint value minus hysteresis counts with FALLING INPUT SIGNAL INITIAL
START-UP INHIBIT.
Note:
If hysteresis set with ZERO counts, relay energizes AT OR ABOVE the setpoint value.
DEVIATION selected –
relay energizes INSIDE deviation band (setpoint ± deviation
counts) with FALLING INPUT SIGNAL INITIAL START-UP INHIBIT. De-energizes OUT-
SIDE deviation band (setpoint ± deviation counts) with FALLING INPUT SIGNAL INI-
TIAL START-UP INHIBIT.
PID selected –
controls ABOVE setpoint value.
3 Energizes BELOW setpoint value with RISING INPUT SIGNAL INITIAL START-UP
INHIBIT
HYSTERESIS selected –
relay energizes BELOW setpoint value plus hysteresis
counts with RISING INPUT SIGNAL INITIAL START-UP INHIBIT. De-energizes BELOW
setpoint value minus hysteresis counts with RISING INPUT SIGNAL INITIAL START-
UP INHIBIT.
Note:
If hysteresis set with ZERO counts, relay energizes BELOW the setpoint value.
DEVIATION selected –
relay energizes OUTSIDE deviation band (setpoint ± deviation
counts) with RISING INPUT SIGNAL INITIAL START-UP INHIBIT. De-energizes
INSIDE deviation band (setpoint ± deviation counts) with RISING INPUT SIGNAL INI-
TIAL START-UP INHIBIT.
PID selected –
controls BELOW setpoint value.
Resetting and Incrementing Using Setpoints
Setpoints may be used to reset and/or increment registers. In the
example shown opposite, 2 liter soft drink bottles are being filled
and packed 12 to a case. Using the setpoint reset and increment
feature, the number of bottles and the total number of filled cases
is easily calculated and displayed. Totalizer 1 counts from 0 to 2,
resets, and repeats. CH2 counts from 0 to 12, resets, and repeats.

Detailed Descriptions of Setpoint Functions
Explanation Of Setpoint Trigger and Reset Functions
The setpoint trigger and reset functions are available on all 6 set-
points. The various parameters of these functions are described
as follows.
Trigger Type
The trigger parameter gives the option of selecting which edge of
the relay operation the reset function, print function, and data log-
ging function should activate on. It can be set to either:
•
Off
– Disables all trigger functions
•
Make
– operates on the make edge only.
•
Break
– operates on the break edge only.
•
Both
– operates on both make and break edges.
•
Level
– operates after every sample period if relay is ON.
Reset Destination
The reset destination parameter defines the target register in the
meter that is to be modified in some way when the reset trigger
conditions for this relay are met. Any Modbus register number
from 1 to 255 can be selected as a reset destination. If the [DEST]
parameter is set to [OFF], the reset function is disabled and the
Reset Mode and Reset Constant/Source selection are not dis-
played during setup. The setup sequence jumps straight to the
Print parameter.
Reset Mode
The reset mode parameter defines what type of reset effect is
required. The following different options are available.
Const
– This mode stores a user defined constant into the select-
ed destination register. In most cases this number will be zero but
it can be any number.
I-S+C
– This mode stores the current input value
I
, defined by the
setpoint source, minus the setpoint value
S
plus a user defined
constant
C
. It would normally be used with a counting or totalizing
application where the amount of setpoint overshoot needs to be
retained after the reset function. The constant value would nor-
mally be zero but could be used to provide an offset if required.
D+C
– This mode adds the user defined constant
C
to the current
value in the selected reset destination register
D
. It can be used
to increment or decrement a register by any amount.
Reg
– This mode copies the contents of a user selectable regis-
ter into the reset destination register (see Reset Constant to select
the source register).
1st Digit in Setpoint Programming Mode
Following is a detailed description of the options available on the 1st digit of
the setpoint programming mode [SPC] settings listed on Page 11.
Relay Energize Function
FIRST DIGIT
It can be used to capture data on an event and store it in an
unused channel for display or analog output, etc.
Reset Constant
This parameter defines the constant value to be used in the
Const
,
I-S+C
,
D+C
modes as previously explained. Its default
value is zero. This parameter is not available if
Reg
is selected as
the reset mode.
Source (only available in Reg mode)
If the reset mode is set to
Reg
then the source parameter allows
you to select the number of the Modbus register in the meter to
be copied to the reset destination register.
