9.6 P5 – SETPOINT OPTIONS
This register defines the output action for SetPoint and Current Loop models. Note that if an output is disabled by
this register the SetPoint value in its corresponding register (P6, P7) has no impact.
In Measure Mode, the indicators “SET1” and/or “SET2” will illuminate when the corresponding relay is energized.
The “4-20mA” indicator will illuminate when the Current Loop output is enabled. In Program Mode, the
indicators “SET1”, “SET2”, and “4-20mA” will illuminate as appropriate to assist when scrolling through the
register’s choices. Note that if P5 is set for active, the outputs will continue to update even in Program Mode,
according to the currently programmed values.
P# Name Description Value Range Notes
SetPoint Model: defines which relay
outputs are active. 0 = Disabled.
1 = SET1 only.
2 = SET2 only.
3 = Both enabled. P5 SetPoint

Current Loop Model: defines the
status of the 4 - 20 mA output. 0 = 4-20 disabled
1 = 4-20 enabled

GAUGE IN MEASURE MODE
1. Press PRGM/ENTER to access P0 prompt
2. If lockout is in-active prompt will be P0
• Increment P# using UP ARROW until P5 is displayed
• Press PRGM/ENTER to access P5 value
• Press the UP or DOWN ARROWS to change the selection
• Press PRGM/ENTER to enter the setpoint option selection
• Press the BACKSPACE to return to MEASURE MODE
3. If lockout is active prompt will be L 00
• Enter Lockout Code then continue as in 2) above
9.7 P6 and P7 – SETPOINT (SET1 and SET2)
9.7.1 Setpoint Model
These programmable registers define the flow values at which the relay outputs will energize. The relay will
energize when the flow exceeds its corresponding value, and de-energize when the flow drops below the value
minus the deadband. Register P6 defines the SET1 relay detection threshold and P7 defines the SET2 relay
detection threshold.
9.7.2 Current Loop Model
These programmable registers define the 4 to 20 mA output scaling and range. The P6, SET1 value defines the flow
rate that will be represented by a 4.00 mA output signal. The P7, SET2 value defines the flow rate that will be
represented by a 20.00 mA output signal. Other flow values provide an output that is linearly scaled between the
two end points P6 and P7. For values beyond the defined range the output is limited from 4.00 to 20.38 mA. The
P6 (4-mA) register can be set greater than the P7 (20-mA) register, to create a reverse acting output. The limits are
–20% to +120% full scale, but P6 and P7 cannot be set at equal values.
