OPERATION
The 342 is a repeat-cycle timer that operates continuously
through its two timing ranges (T1 and T2), one after the other,
transferring the relay contacts as it times out of each range. There
is no start circuit and the timer resets on power interruption. The
first timing range (T1) begins and the relay is energized when line
voltage is applied to the Run terminals of the 342. The relay is de-
energized when T1 times out and it remains de-energized until T2
times out ... at which time the relay is energized and the flip-flop
cycle is repeated. The pattern of relay operation can be reversed
— de-energized during T1 and energized during T2 — by chang-
ing a push-on connector from one pin to another on the circuit
board; no wiring change is required.

Repeat cycle: resets on power interrup-
tion. DPDT relay can be energized either
during the first timing cycle (T1) or during
the second (T2) simply by moving the
PCB jumper.
Six independent continuously adjustable
switch-selected ranges for each timer:
