Stroke Time Alarm Adjustment Procedure
CAUTION:
Valve/Actuator will automatically stroke
while performing this procedure.
1. Read all instructions prior to performing this proce-
dure. The Stroke Time Alarm is adjustable from 1 to
60 seconds. AS-Interface communications is not
needed to perform this procedure, however, a 24 V
dc power source connected to the ASI+ and ASI-
and an air source of a minimum of 2.8 bar connected
to the Axiom supply pressure port (Port 1) will be
required.
2. Ensure the CLOSED and OPEN sensors have been
set. If not, perform the sensor setting according to
instructions located below.
3. With the valve/actuator in the closed position, verify
there are no fault indications, then press and hold
both the SET CLOSED and SET OPEN buttons until
both the CLOSED and OPEN LED’s are lit (2 sec-
onds). Release both buttons, the red CLOSED LED
should be flashing.
4. Push the SET CLOSED button to start the Timer func-
tion. The valve/actuator will automatically open and
the OPEN LED start to flash.
5. After the valve/actuator has fully opened, wait the
desired time the Stroke Time Alarm is to be set to (1
to 60 seconds), then push the SET OPEN button.
This will stop the Timer function and the valve/actua-
tor will automatically go back to the closed position.
6. The unit is ready to resume normal operation.
Remote Sensor Setting Feature
The Axiom with Diagnostics provides the capability of
setting the Closed and Open sensors remotely from the
Control System or from the AS-Interface Gateway/Mas-
ter.
1. AS-Interface communications are required in order
to remotely set the sensors. The unit must be
addressed and correctly configured to be recog-
nized by the Control System or the AS-Interface
Gateway/Master.
2. With the valve/actuator in the closed position, set
Output Bit 1 (DO 0) to “1” for at least two seconds.
This will set the Closed sensor to that valve/actuator
position. Set Output Bit 1 (DO 0) back to “0”
3. With the valve/actuator in the open position, set Out-
put Bit 2 (DO 1) to “1” for at least two seconds. This
will set the Open sensor to that valve/actuator posi-
tion. Set Output Bit 2 (DO 1) back to “0”.
The “Wink” Feature
The Axiom with Diagnostics provides the capability of
setting the CLOSED and OPEN LED’s to simultaneously
flash or “wink” . This feature aids in physically locating
the unit on the network.
1. AS-Interface communications are required in order
to set the “Wink” feature. The unit must be addressed
and correctly configured to be recognized by the
Control System or the AS-Interface Gateway/Master.
2. Set Output Bit 4 (DO 3) 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 LED’s, set Output Bit 4 (DO 3)
back to “0”. Performing this function will not change
the Closed and Open sensor set points.
