Monitoring system for ice making machine
First Claim
1. A monitoring system for a plurality of ice making machines each of which includes an ice making mechanism, a detection device for detecting operating condition of the ice making mechanism and control means for electrically controlling operation of the ice making mechanism in accordance with the detected operating condition,wherein the ice making machines each are provided with output means for issuing electric signals respectively indicative of the detected operating condition and an identity number for identifying each type of the ice making machines outwardly, andwherein the monitoring system comprises a signal receiver for monitoring each operation of the ice making machines on a basis of the electric signals applied thereto from said output means, said signal receiver including means responsive to the electric signals for determining each of the ice making machines as being operated in an abnormal condition if the detected operating condition becomes abnormal in comparison with a control data for the ice making machine identified by the identity number and alarm means for informing an operator of the abnormality in operation of the ice making machine identified by the identity number.
