the Cycle Time. Thus, a Cycle Timer will
energize the Relay Output for a set amount of
time (ON.TIME) and de-energize for the
remainder of the cycle (CYC.MIN). This cycle
repeats until the Setpoint condition is no
longer met. For more information on the Cycle
Timer, see Section 2, Overview.
Valid Setpoint values are limited to the

Valid Cycle Time and On Time values are 0.0 to
99.9 minutes.
