REMOTE CONTROL INPUT: 

 
TB 1 (located on upper board) also has provisions for 120 VAC Remote Control Signal.  This 
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.   

 
FEATURES:

 

 

 

120 VAC  50/60 Hz, One phase  

 

One amp maximum capacity per output 

 

One amp fuse protection 

 

All solid state industrial quality construction 

 

Illuminated Digital indication of next output to fire, and indicates timer operation. 

 

Adjustable ON time  50 - 150 ms 

 

Proportional OFF time, minimum of 3 sec.   

 

Settable OFF time:  3-120 sec. If in Hold Off Mode.  

 

Remote switching between Continuous Clean and 

Δ

P control 

 

Differential set point, adjustable 2 to 6 in. H

UL Recognized to US and Canadian Standards under File E 60685 

 
 
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.
