| Rotor Stop Option (Countdown on Hold) | A rotor stop option is available to override the timing action or to hold the timer valve in its switched position after the timer has completed its cycle, and signal pressure is removed. Option provides 2 additional rear ports connected via tube, which allows valves or other logic devices to be spliced into the internal circuit between the pilot signal regulator and rotor assembly.
For holding timer valve in its switched position or to place “timing on hold”, an external 3 way valve (NO)can be used to block the flow to the air motor(connected between rotor stop ports 1-2). If timing on hold is desired, the pilot signal must remain on throughout the entire cycle. |
| Power Connections | For installations requiring larger valves, use the standard timer and connect a pneumatically operated single air piloted 3 or 4 way valve of the size required to the timer output. Contact factory with size requirements. |
| Typical Circuits | See typical timing circuit diagrams at the end of the timer catalog section for help in constructing pneumatic timer circuits. |
| Diagrams | Timer output valve is 4 way, 5 ported with 10-32 (M5) connections. Valves are supplied from factory blocked with a cap nut (port 4) for 3 way off delay. For on delay, move cap nut to port 2. For full 4 way operation remove nut. |
