7 INITIAL STARTUP NO LOAD ALARM FUNCTION ENABLING: When the GSL is turned ON, the control operates to fill the ‘hopper’ being loaded. To avoid nuisance alarms, the NO LOAD ALARM is not enabled until the demand has been satisfied as follows: The 'demand' input remains off for the ‘Demand Timer’ (Dump Time plus ~5 seconds). The control assumes this timing sequence indicates the ‘hopper’ has completed an initial fill process.
8 ELECTRICAL CONNECTIONS FOR LOADER OPTIONS -Proportioning Valve -Purge Valve -Output to Auxiliary Alarm Device 1.
