Maintenance Timer - Magnetek Impulse G+ series 4 Instruction Manual

Maintenance Timer

The "Maintenance Timer" is a maintenance feature that will alert an operator, for example, when the
bearings need to be greased. It consists of a Multi-Function Output (H02-0x–08 = 37) that becomes
active when the total running time has exceeded the amount of time (in hours) programmed in
parameter C12-05 and the frequency reference will be multiplied by a programmable gain (C12-06)
to slow the motion down until the bearings have been greased. An alarm will also be posted on the
Keypad stating "Maintenance Required". Once the bearings have been greased, the output and
alarm message can be reset by two different methods. One method is through a Multi-Function Input
programmed for Maintenance Reset (H01-01–08 = 5A) and the second method is by pressing the
Mode/Service (Local/Remote) button three consecutive times with no more than 2 seconds between
presses. Press enter to reset the timer. A message will then appear on the keypad stating that the
timer has been reset. The Multi-Function Output will turn off at this time. When C12-01 = 0, the
function is disabled.
