When using ½” conduit, the strain relief fitting must be removed from the enclosure.
Make sure that any conduit or metal fittings do not come in contact with the circuit board.
ZERO FUNCTION
The DLP unit should be “ZEROED” before pressure is applied to the unit.
The zero button is used to cancel out any offsets caused by installation and sensor drift.
The Zero adjustment must be performed with NO pressure applied to either side of the sensor.
Remove the tubing connected to the H(High) and/or L(Low) pressure fittings.
Push “
ZERO
” button for more than three seconds before installation or whenever necessary.
For units with LCD display:
“AUTOZERO” icon will be on when the unit enters zero mode. If zeroing process is successful, the
“AUTOZERO” icon will flash twice.
PRESSURE RANGE SELECTION
If a custom calibrated range is ordered, DO NOT change Range Selection DIP switch settings.
The DLP can operate in either unidirectional mode (0 – X inWC) or bidirectional mode (± X inWC). Each unit could have up to eight
field selectable, uni or bidirectional ranges.
DO NOT SWITCH PRESSURE RANGE OR OUTPUT MODE WHEN POWER IS ON
.
MAKE SURE POWER TO THE UNIT IS OFF.
FAILURE TO DO SO WILL NOT ALLOW ANY NEW SWITCH SETTINGS TO TAKE PLACE.
