8.2 Analog Input Calibration
If you are not using the 4-20mA input to the MPC for control, skip this section. To calibrate the Input
Current you must first correctly wire an external signal source. Refer to Section 5 – Installation: Low
Voltage Input Connections, Analog Input. To perform a calibration, the signal-generating device must
be active and capable of generating the full range (low to high) of potential input signals.
1. The starting display will be:
SETPT XX.XXX
FLOW XX.XXX
2. Press the MENU key
-MENU-
CALIBRATION
3. Press the ENTER key
CALIBRATION
PUMP FLOW
4. Press the UP arrow key twice, to access the analog input calibration
CALIBRATION
ANALOG INPUT
5. Press the ENTER key
APPLY MIN MA
ENTER TO START
6. Apply your desired minimum mA control signal to the MPC (usually 4 mA)
7. Press the ENTER key
MIN SETPT X.XX MA
SPEED 000.0%
(The mA value will be equal to your input signal level)
(The speed value is the setting the MPC will use for this signal value)
8. Press the ENTER key three times to step through the speed setting value, most users will leave
this at 000.0 %, however you an change it if you wish using the UP and DOWN arrows.
9. Press the ENTER key once more to accept the calibration value
APPLY MAX MA
ENTER TO START
10. Apply your desired maximum mA control signal to the MPC (usually 20 mA)
