Example No. 4

Operation of On\d (On with off delay) override input

Assume that off delay time is programmed for 1 hour. Also assume that the channel’s pro-
grammed state is off.

Example No. 5

Operation of OVr (toggle) override input

Assume that the channel is currently under control of a duty cycle event.

Case 1

: No programmed ON time (ONt = 0:00.00)

NOTES:  1. OVr can be canceled from the keyboard override mode.

2. Toggle override will end when the next programmed event is reached.

3. OVr input is active with the closing of the input. Opening the input has no effect.

Case 2

:  Programmed ON time = 1 hour

NOTES:  1. OVr ON cancels after 1 hour, unless OVr input is closed again which will force an 

override OFF.

2. OVr OFF can be canceled from the keyboard override mode.

3. OVr input is active with the closing of the input. Opening the input has no effect.
