The power input is protected by a 600mA M (medium time-lag) resettable 
fuse.  If a shorting condition or polarity reversal occurs, the fuse will cut 
power to the valve circuit.  Disconnect the power to the unit, remove the 
faulty condition, and reconnect the power.  The fuse will reset once the 
faulty condition has been removed.  
 
Use of the Optical Sensor Switch in a manner other than that specified 
in this manual may impair the protection provided by the equipment.
