Under normal conditions the PWR light is on indicating power is at the control module:
If PWR light is not on, check the drum switch connections.
Under normal operation the IN light brightens and dims as the feed rate switch is turned
up and down:
If the IN light is always on or always off, the feed rated switch could be wired incor-
rectly,
If the IN light is erratic, the feed rate switch is worn.
Under normal operation the OUT light brightens and dims (same as the IN light) as the
feed rate switch is turned up and down:
If the OUT light does not correspond with the IN light, check if the OV or OL lights
are on,
If the OV or OL lights are not on, replace the control module (Part No. 024396-1).
Under normal conditions the OV light should never be on:
