Changing or Checking Time Programs

By operating the Prog. button, the individual commands as programmed can, at any time, be brought consecutively into the display for revision or checking. Revisions are accomplished by programming over the existing programs using the steps at the left.

Canceling Time Programs

After the selecting the desired program, use the h and m buttons to set hours and minutes to zero; the ––:–– will be displayed. This program has been made ineffective and will no longer be carried out. To cancel all programs, press the Res. (reset) button. This clears all memory including the time base and program storage.

Manual Override

Do not manually override the exerciser unless you are sure that the controller has been set for exercise without load (see page 5–2). Failure to do so could result in possible injury if the transfer switch operates while the enclosure door is open.
