4.14.3 Contact
This mode allows the user to select the state of the contact when the function is active. Select “NO” to choose whether
the contact is required to be normally closed, normally open, or blinker when the function is active. When “Blinker” has
been selected, the contact will switch automatically between open and close (1 second open/1 second close).
4.14.4 Valve Position
This display will appear only if the function “MID-TRAVEL POSITION” has been selected. Toggle “NO” until the display
indicates the required value of percentage “OPEN” at which the contact should trip. If the contact has been selected as
normally closed, then it will close when the trip point has been reached, with the actuator moving in the open direction.
NOTE: Status contacts (S) and optional alarm (R) contacts are latching type and will remain in their last set position in
the event of a main power supply failure.
4.15 Two-speed Timer (Optional)
The optional two-speed timer extends the operating time of the actuator, in the closing and/or the opening direction,
by pulsing the motor ON and OFF. Pulsing may be applied to full valve travel or only a part of it. The ON and OFF pulse
times are adjustable.
1. Select “CHANGE 2-SPEED TIMERS?”
2. Select “YES” to enter the “CHANGE OPEN TIMER?” routine.
3. If slow opening is required, select “YES;” otherwise select “NO” to move into the “CHANGE CLOSE TIMER?”
routine.
4.15.1 Status
Select “NO” to switch the timer ON or OFF. If OFF, no further menus will be displayed.
4.15.2 Start Position
If the Close or Open timer has been switched ON, pulsing will start when the set point is reached in the selected direc-
tion and the actuator will continue pulsing until the valve reaches the desired “STOP” position.
