Online Adjust Mode

To enter

Online Adjust Mode

, press the

<PGM>

key for at least 3 seconds. Online Adjust Mode allows

you to set the Null, Gain and PWM Offset values.

Note - Due to possible voltage drops across the cables, the Null and Gain value should also be checked
at the input of the controller with a 6 digit multi-meter for accuracy. The voltage value on the display
represents the Analog Output Voltage seen directly on the Output of connector J1, pin “D”

Adjust Null -

Locate the magnet to the Null location, towards the housing of the

transducer. The Null value may adjusted anywhere between -10 Vdc & +10 Vdc.
Press the

<UP>

key to increase the Null, press the

<DOWN>

key to decrease the

Null. The Analog Output Voltage is updated accordingly on the display. Press

<PGM>

to continue to the next parameter.

Note - If no transducer is detected on power up, the display will show 0.000 V

Adjust Gain -

Locate the magnet to the Gain position, towards the end of the trans-

ducer rod (side that is away from the transducer housing). The Gain value may be
adjusted anywhere between -10 Vdc & +10 Vdc. Press the

<UP>

key to increase

the Gain, press the

<DOWN>

key to decrease the Gain

The Analog Output Voltage

is updated accordingly on the display. Press

<PGM>

to continue to the next pa-

rameter.

Note – If no transducer is detected on power up, the display will show 0.000 V

Note – It may be necessary to repeat the Online Adjust Mode steps 1 and 2 until the voltages re-
quired at the Null and Gain locations are set to desired values.

Adjust PWM Offset

This step allows the pulse width of the PWM output signal to

be adjusted. To setup the PWM signal, locate the magnet at the NULL location.
Pressing the

<UP>

key will increase the pulse width of the PWM signal, pressing the

<DOWN>

key will decrease the pulse width. The PWM pulse width is updated ac-

cordingly on the display.

Note -

This step is not needed if only the analog output

is being used.
