Wink feature
The Wink feature provides the capability of setting the closed or open
LEDs to flash or wink at a 2 Hz rate. This feature aids in physically
locating the unit on the network. It does not change valve state
indication in the control system.
Bench test procedure and sensor setting instructions
1. To test sensors, it is best to connect to an AS-i bus using an
AS-i power supply so that communication can also be tested.
However, if a network is not available, to set the open and closed
set points, use a 24 VDC power supply. Connect 24 VDC+ to
AS-i+ and 24 VDC- to AS-i -.
2. Attach indicator such that the closed quadrants will face out when
in the closed position. This figure shows a Red Closed visual
indicator in the closed position.

Save set-points:
a.
Operate actuator to the closed position.
b.
Press and hold SET CLOSED button until closed LED is lit (2
seconds). Release button.
c.
Operate actuator to the open position.
d.
Press and hold SET OPEN button until the open LED is lit (2
seconds). Release button.
NOTE: If red or green LEDs flash when trying to set the set-point,
the magnet is too far away from the sensing element. Adjust Visual
Indicator drum to bring the magnet slightly closer to the sensing unit
and try again.
3. Setpoints are retained even after power is removed.
4. To electrically test the solenoid output, the unit should be
connected to an AS-i bus and commanded to turn on. Optionally,
the solenoid can be energized via the Bluetooth app if the device
is configured with Bluetooth capability and is unlocked.
Note
If using only one of the sensors for valve position feedback, either
sensor may be used independently.
WARNING
DO NOT APPLY EXTERNAL POWER TO THE OUTPUT
TERMINALS. THIS WILL CAUSE PERMANENT DAMAGE TO
THE UNIT.
Caution:
Performing this procedure will cause the
sensor inputs to change state. Performing this procedure
is not recommended during a live process.
