Programming notes
Press and hold key for 3 seconds to enter manual control mode (MCTL).
The display will count down the 3 seconds.
Press the
key to enter the current calibration mode (C-CAL). Press to
return to
MANOP.
In MANOP press key to advance to autostroke (AUTOS).
Commissioning notes
Before initiating an autostroke commissioning (AUTOS) use manual control (MCTL) to
manually fully inflate and deflate the actuator to ensure there are no obstructions to the full
valve travel movement.
Manual control is also useful during normal operation to manually control the valve position
as a commissioning aid or in the event of input signal failure.
9.3.1 MCTL - manual control
Programming notes
Manual control enables the actuator to be manually inflated or deflated.
Press key to inflate actuator and key to deflate the actuator. Press and
hold or key to accelerate action.
Prior to undertaking an AUTOS the display will indicate FILL or VENT.
On completion of AUTOS the display will indicate % valve travel.
Manual control (MCTRL) - Tight shut-off function
Press and hold the key to drive the valve to its closed position. At 0% travel the
! will flash to indicate limit of travel. To initiate tight shut-off release the key and
press again. The actuator will be vented of air to provide dead tight shut-off.
This also applies to the 100% valve position by pressing and releasing the key
and pressing again to inflate the actuator to provide dead tight shut-off.
Manual control (MCTRL) - Travel limits
When operating in manual control any travel limit settings will be overridden
therefore it is possible to manual position the valve through its full 0 to 100%
travel as measured in autostroke (AUTOS).
Commissioning notes
Before initiating an autostroke commissioning routine (AUTOS) the actuator should be
manually fully inflated and deflated to ensure there are no obstructions to the full valve travel
movement.
Manual control is also useful during normal operation to manually control the valve position
as a commissioning aid or in the event of input signal failure.
