DeviceNet™ Wink feature
The Wink feature provides the capability of setting the CLOSED and
OPEN LEDs to simultaneously ash or wink at a 2Hz 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 congured 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 CLOSED and OPEN LEDs, set byte 0 bit 2 back to0.
Performing this function will not change the closed and open
sensor setpoints.
Quartz with DeviceNet™ Fault Bit (input byte 0, bit 7)
1. The Fault indication will set to a 1 when input byte 0, bits 0 and 1
are set to 1 at the same time.
2. 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.
