VP100 VALVE POSITIONER CALIBRATION PROCEDURE
Step 1: Electrical Connection.
Before connecting power always check the label for the power supply it has been
configured for.
If the unit you have been supplied with is for 240VAC operation then connect AC
power to:
(a)Terminal 3 is 240VAC supply
(b)Terminal 2 is neutral VAC supply
(c)Terminal 1 is ground supply
If the unit you have been supplied with is for 120VAC operation then connect AC
power to:
(a)Terminal 3 is 120VAC supply
(b)Terminal 2 is neutral VAC supply
(c)Terminal 1 is ground supply
If you require to change an instrument from 240VAC to 120VAC or 120 to 240VAC
operation then there are 3 solder links on the circuit board underneath the transformer.
These links are shown on the component overlay as LK1, LK2 and LK3.
For 240 VAC operation: close link LK2 and open LK1 and LK3
For 120 VAC operation: close link LK1 and LK3 and open LK2
If the unit you have been supplied with is for 24VDC operation then connect DC
power to:
(a)Terminal 3 is 24VDC supply
(b)Terminal 2 is 0VDC supply
(c)Terminal 1 is ground supply
Connect the feedback potentiometer on the valve to:
(a)Terminal 10 is feedback pot left side
(b)Terminal 11 is feedback pot wiper
(c)Terminal 12 is feedback pot right side
The feedback potentiometer can be any value between 100 Ohm to 10,000 Ohms
Connect the milliamp command signal to:
(a)Terminal 8 milliamp loop positive (+)
(b)Terminal 9 milliamp loop negative (-)
Connect the Valve Motor to:
(a)Terminal 4 is Motor One (Forward)
(b)Terminal 7 is Motor Two (Reverse)
(c)Terminal 5 or 6 is the Motor Supply Active
The voltage active supply on terminals five (5) or (6) is switched by the internal relays
on to terminal 4 or terminal 7.
Calibration of the instrument
To gain access to the adjustment potentiometers it is necessary to remove the front
plate of the instrument.

Step 1.
(a) You will see there is a 1mm gap on the right hand side between the front plate and
the case. Insert a thin bladed screwdriver into this gap and gently prise out the front
plate. Access to the calibration potentiometers is now available.
Step 2: Calibrating the feedback potentiometer
The feedback potentiometer is displayed on the two digit LED display at the front of
the instrument as 00 to 99
(a)Drive the motor to its minimum position so that the feedback pot on the motor
gives out its minimum resistance value. Adjust the FEEDBACK ZERO (p2) pot
until the display reads '00' or the minimum required value.
(b)Drive the motor to its maximum position so that the feedback pot on the motor
gives out its maximum resistance value. Adjust the FEEDBACK SPAN (p1) pot
until the display reads '99' or the maximum required value. Repeat until the required
reading has been reached.
Step 3: Calibrating the input current loop.
The instrument can be set up to accept either a 4-20mA or 0-20mA input signal. All
instruments are shipped for 4-20mA operation. If it is intended to use an 0-20mA
input signal then remove the link marked R39 on the electronics board. (There are
two main circuit boards, a power supply/relay board and an electronics board).
(a)Drive the motor to its minimum position and inject 4mA. Adjust potentiometer
COZ CONTROL OUTPUT ZERO (p5) until the relay changes state.
(b)Drive the motor to its maximum position and inject 20mA. Adjust potentiometer
COS [CONTROL OUTPUT SPAN] (p3) until the relay changes state. Repeat the
steps 4 (a) and (b) once for confirmation of the correct operation.
Step 4: Calibrating the Dead band
Dead band of the relay switching operation can be set between 1 to 25%. This is
accomplished by adjusting the DEADBAND POTENTIOMETER (P4)
AUTO MANUAL SELECTION
The instrument also includes auto/manual control of the final element. The three push
buttons that protrude through the front of the instrument are:
(a)CENTRE BUTTON - Auto/manual selection
(b)LEFT BUTTON - ramp down
(c)RIGHT BUTTON - ramp up
The instrument is in AUTO when the centre button is extended and in MANUAL
when the centre button is pushed in.
In AUTO the VP100 tracks the 4-20mA signal driving the motor to a position relative
to the 4-20mA signal.
In MANUAL the VP100 ignores the 4-20mA signal and the motor can be manually
driven by using the RAMP UP/RAMP DOWN push buttons which switch voltage
directly onto the motor bypassing the internal electronics.
