TROUBLESHOOTING
If the EFC provides inconsistent timing or sensing, it might be located in an area with excess electronic noise. Under these
conditions, separate the timer control unit, wiring, and sensor cable (which generates the input signals) as far as possible from the
noise source(s). To further prevent electronic interference, shield the sensor cable.
If there is power to the EFC but the power switch does not light, it is possible that the internal fuse has blown. To replace the fuse,
first, unplug the unit (remove power). With the cover removed, a modular plastic fuse housing is visible. The door of the housing
opens to the side. The fuse holder is rated 5 amps. Replacement fuse is BUSS AGC 5A rated 250V.
The relay has a life expectancy 100,000 operations minimum. (This is based on 5A at 250VAC, with a resistive load at 360
operations/h.)
CLEANING, MAINTENANCE AND STORAGE
Periodically inspect the EFC unit, wiring and parts for damage. If any damage is observed, do not use the equipment and contact
EXAIR for replacement parts as applicable.
If it becomes necessary to replace the fuse, use a ¼” x 1-1/4” (6.4mm x 32mm) 5A, 250V Fast Acting fuse.
Organic solvents such as paint thinner, as well as very acidic or basic solutions can damage the outer casing of the timer. Clean
with a soft cloth or mild detergent.
When storing the EFC, make sure that the ambient temperature and humidity are within the rated values. If the EFC has been
stored at an ambient temperature of -10°C or below, the unit must sit at room temperature for at least three hours before using it
for the EFC to function properly.
