Mamac Panel-Mounted Pressure Transducer
WARNING
Electric shock hazard. Can cause personal injury or equipment
damage.
This equipment must be properly grounded. Connections and
service to the MicroTech III control panel must be performed
only by personnel that are knowledgeable in the operation of
the equipment being controlled.
The following describes the proper wiring of these pressure
transducers with mA output.
1. Remove the terminal block by carefully pulling it off the
circuit board.
2. Locate the [+] and [-] terminal markings on the board.
3. Attach the supply voltage to the [+] lead.
4. Connect the 4-mA output ([-] terminal) to the controller’s
input terminal.
5. Ensure that the power supply common is attached to the
common bus of the controller.
6. Re-insert the terminal block to the circuit board and apply
power to the unit.
7. Check for the appropriate output signal using a DVM set
on DC milliamps connected in series with the [-] terminal.
