Grasslin Digital Programmable Generator Exercise Timer

SETTING UP THE DIGI 20A AS AN EXERCISE TIMER - A QUICK OVERVIEW

The Grasslin DIGI 20A time switch is an ideal choice as a generator exercise timer because of its low cost, ease of programming, reliability and extended memory protection (4 days min. without power). Although the DIGI 20A can accept up to 20 “on” and “off” events in a week, typically only one “on” and one “off” event is required for generator exercise use. The duration of the exercise period is simply the elapsed time between the “on” event and the “off” event. Please refer to the instruction sheet enclosed with unit for details. After installation, the timer is programmed with the following steps.

Initial reset after powering on.
Select AM/PM or 24-hour (military) time.
Set the time of day (includes standard/daylight option).
Set the exercise start time.
Set the exercise stop time.
Verify settings.

Settings may be changed or deleted at any time. Programmed information will be retained at least 4 days without power. The DIGI 20A has a manual override feature that permits running the generator from the timer without disturbing the programmed information. Please refer to the enclosed instructionsheet for details of programming steps, verification and the meaning of the display icons.
