input enables the timer to be switched remotely between the 4-20 mA mode and the
continuous cycle mode.
PULSE OUTPUT:
TB 2 (located on lower board) provides a 120 VAC signal every time an output is pulsed.
This can be used to monitor timer operation or count pulses.

MOUNTING AND GENERAL WIRING:
1. Each timer is to be mounted in a dust tight and water tight NEMA rated enclosure.
2. It is recommended that conduit openings/holes be placed in the bottom of the enclosure
to prevent condensate or moisture from entering enclosure.
3. Mount the timer enclosure in a vibration-free area. (Use isolators to mount timer to sub
plate.)
4. Run supply wiring to the timer, 120Vac, 1 Phase, 50/60 Hz from the line circuit protector.
5. Run wiring from the timer to the pilot valve box.
6. SWITCH (SW1) position must be placed per mode of operation desired.
