Sea Frost 372 ROUTE manual Troubleshooting

TROUBLESHOOTING

A light emitting diode (LED) is connected between terminals + and D. In case the electronic unit records an operational error, the diode will flash a number of times. The number of flashes depends on what kind of operational error was recorded. Each flash lasts 1/4 second. After the actual number of flashes there will be a delay with no flashes, the sequence for each error recording is repeated every 4 seconds. Flashes will only occur in the fault mode with the system on.

OPERATIONAL ERRORS SHOWN BY LED

Number of	Error type
flashes
5	Thermal cut-out of electronic unit (If the refrigeration system
	has been too heavily loaded, or if the ambient temperature is high,
	the electronic unit will run too hot).
4	Minimum motor speed error (If the refrigeration system is too
	heavily loaded, the motor cannot maintain minimum speed 1,850
	rpm).
3	Motor start error (The system is overcharged).
2	Fan over-current cut-out (The fan is defective).
1	Battery protection cut-out(The voltage is outside the cut-out
	setting. Low voltage.)
