Installation and Operation
Mounting
The Unit may be mounted in any position
through the use of the two mounting holes and
8 - 32 screws (See figure 2 for unit dimensions).
Wiring
The one shot must be wired as shown in Figure
3, otherwise the control will not function
properly.
1. Wire AC line voltage through fuse to yellow
connector as shown.
2. Wire solenoid coil to green connector as
shown.
3. Wire switching circuit (relay contacts) to
white, red and black connectors as shown.
When the switch/relay is actuated, the solenoid
coil is energized by the pulse from the internal
capacitor discharging. When the switch/relay is
released or deactivated the internal capacitor is
charged for the next cycle. The minimum time
between operations is 15 milliseconds.
