Jumper Notes
Port Swap/Norm Reverses polarity of the pressure ports (i.e. makes the LO port
operate as the HI port and vice versa); used when the sensor is
incorrectly plumbed.
Bi-Dr/Normal Normal: 0 to F.S. pressure
Bidirectional: -F.S. pressure to +F.S. pressure; output reads 1/2 when
pressure is zero.
Slow Avg/Fast Norm Slow mode provides 5 second averaging for surge damping.
Analog Rev/Norm Normal: output increases as pressure increases;
Reverse: output is maximum when pressure differential is zero and
decreases as pressure increases.
Bar/PSI Select output units.
Optional: Connect Zero terminals to digital output (contact
closure) of control system.
Caution: Zero input is for dry-contact only. Do not apply voltage to
the Zero terminals.
Range: Use the Range switch to select
F.S. differential pressure.
Auto-Zero: Press and hold the Zero button for 2 seconds or provide contact closure on
the auxiliary ‘Remote Zero’ terminal to reset the output to zero pressure. To protect
the device from accidental zeroing, this feature is only enabled when the detected
pressure is within 5% of factory calibration.
Note: Use of a
housing grounding
screw is required
for CE applications
