Fig. 58. Setup - Outputs - Options - Schedule.

2.3.3.1. USE SCHED

Press the

button to display the schedule

selections.

Use the

and

buttons to highlight YES or NO.

Default: NO

Press the

button to accept the value and display

the MIN OFF option.

Selecting NO disables scheduling for

all

outputs.

Selecting YES enables scheduling for

all

outputs. When

YES is selected, all individual outputs default to follow the

schedule. However, each individual output can be

removed from scheduling as desired.

With Scheduling enabled, when you return to Program

mode, the new option for Scheduling displays. You can

press the home key and then the menu key to view the

Schedule options in the menu.

See “2.3.1.5. SCHEDULE” on page 23.

Fig. 59. Setup - Outputs - Options - Min Off/On Time.

2.3.3.2. MIN OFF or MIN ON

This is the minimum number of seconds of “off time” or

“on time” for

all

relays.

Press the

button to display the Min Off/On value.

Use the

and

buttons to increase/decrease

the desired number of seconds from 0 to 990 sec-

onds in 10 second increments.

Default: 0 (zero)

Range: 0 to 990 seconds

Press the

button to accept the seconds and

display the DI OPTIONS.

NOTES:

The minimum OFF or ON time applies to

all

relay outputs.

When minimum OFF or ON time is active,

relays waiting to be energized display a

flashing square underneath the relay number

on the home screen.

If the minimum OFF time is not equal to zero

(0), the minimum OFF time activates at

power-up. To manually override, press the

button at any time.
