BAPI Low Range ZPM Installation & Operations

38926_ins_ZPM_LR
Identification and Overview
BAPI's ZPM is designed for quick
and easy field installation. The
outputs, ranges, units, directionality,
and response time are quickly set in
the field with no tools, no power and
no small components.
The optional LCD display helps with
troubleshooting because it displays
the actual differential pressure
over the entire operational range
regardless of which pressure range
is selected for output to the system
controller. Three LEDs on the
face of the unit indicate when the
pressure is "Out of Range Low", "In
Range" or "Out of Range High".
Switch Setup - Outputs, Ranges, Units/Response
Do not have power applied to unit when changing settings. After changing settings, apply power and Auto-Zero
the unit in its orientation of operation.
