4.2.1 VCT with DeviceNet™ communication (92S & 92W) continued
Caution:
Power cycling unit with Byte 0, Bit 3 or Bit 4 set
will cause the sensor(s) to set at that valve position. Ensure
Byte 0, Bit 3 and Bit 4 are reset to 0 after performing a
remote sensor setting.
Remote sensor setting feature
The Remote Sensor Setting feature provides the capability of setting
the closed and open sensors remotely from the control system.
1. DeviceNet™ communications are required in order to remotely set
the sensors. The unit must be addressed and correctly congured
to be recognized by the control system.
2. With the valve/actuator in the closed position, set byte 0, bit 3 to
“1” for at least two seconds. This will set the closed sensor to that
valve/actuator position. Set byte 0, bit 3 back to “0”
3. With the valve/actuator in the open position, set Byte 0, Bit 4 to “1”
for at least two seconds. This will set the open sensor to that valve/
actuator position. Set byte 0, bit 4 back to “0”
Wink feature
The Wink feature provides the capability of setting the closed or open
LEDs to simultaneously ash or wink at a 2Hz rate. This feature aids in
physically locating the unit on the network.
1. DeviceNet™ communications are required in order to set the Wink
feature. The unit must be addressed and correctly congured to be
recognized by the control system.
2. Set byte 0, bit 2 to “1” in the desired unit. Once the correct unit has
been physically located on the network, indicated by the winking
of the LEDs, set byte 0 bit 2 back to “0”. Performing this function
will not change the closed and open sensor setpoints.
Fault Bit (input byte 0, bit 7)
The Fault Bit will set to a 1 when input byte 0, bits 0 and 1 are set to 1
or 0 at the same time.
When input byte 0, bits 0 and 1 are both set to 1, this would indicate
that the valve is both open and closed at the same time. This would
be an abnormal or Fault condition.
