Expanded dead band setting feature
The Prism PI sensing module has the capability of changing the dead
band of the open sensor from the factory setting of 30% of stroke
to an expanded setting of 45%. It may be necessary to perform this
procedure for applications in which the valve stroke varies between
normal batch processing and SIP/CIP evolutions.
1. Ensure the open and closed sensors have been set before running
this procedure. Valve can be in either the open or closed position.
2. With power applied to the Sensing Module press and hold both
SET OPEN and SET CLOSED buttons until the red and green LEDs
ash (ve seconds). Release buttons.
3. Press and hold SET OPEN button until the green LED is lit (one
second). Release button. Open sensor now has a 45% dead band.
4. To revert back to the factory default of 30% dead band, press and
hold both SET OPEN and SET CLOSED buttons until the red and
green LEDs ash (ve seconds). Release buttons.
5. Press and hold SET CLOSED button until red LED is lit (one second).
Release button.
6. Settings are retained even after power is removed.
Caution: Performing this procedure will cause the sensor
inputs to change states. Performing this procedure is not
recommended during a live process.
Attention: Any external auxiliary device connected to the
VCT module shall be ground isolated.

Bit mapping
Inputs (3 bytes)
Byte 0, bit 0 = red LED / valve closed
Byte 0, bit 1 = green LED / valve open
Byte 0, bit 7 = fault bit
Byte 1, bits 8-15 = 4-20 mA analog input
Byte 2, bits 16-23 = 4-20 mA analog input
(4-20 mA analog input 0-10,000 scaling)
Outputs (1 byte)
Byte 0, bit 0 = solenoid 1
Byte 0, bit 1 = solenoid 2
Byte 0, bit 2 = wink
Byte 0, bit 3 = remote set closed
Byte 0, bit 4 = remote set open
Byte 0, bit 7 = wireless link enabled
Bench test procedure and sensor setting instructions
To test sensors, use a 24VDC power supply. No series load resistor is
required.
1. Apply power across the V+ and V- terminal points.
2. Operate actuator to the closed position.
3. Press and hold SET CLOSED button until red LED is lit (2 seconds).
Release button.
4. Operate actuator to the open position.
5. Press and hold SET OPEN button until green LED is lit (2 seconds).
Release button.
6. Setpoints are retained even after power is removed.
A functioning DeviceNet™ network is required to test
communications and solenoids.
WARNING
Do not apply external power to the output terminals. This will
cause permanent damage to the unit.
