Curtis Computer 1604, 1608 manual Installation, Indication Lights

3.Restart: If the battery self-discharges below 12.9V for 12V batteries or below 25.7V for 24V batteries while the charger is in standby, the charger cycles into a constant current of 1.0A (4A models)/2.0A (8A models) until the constant voltage setpoint is reached. The unit will regulate and terminate as in Constant Voltage Mode.

2.8Indication Lights

The charger features built in diagnostics. Refer to the table below to interpret the flashing of the yellow and green indicator lights. Flashing of the yellow indicator means that the charging cycle has ended early and the battery may not be fully charged. Refer to the Troubleshooting section to correct these faults.

Flash Pattern	Indication
Yellow on	AC power present
Green on	Charge complete
Green blinking	Charging
Yellow & Green on simultaneously	Charger in standby mode
Yellow & Green blink simultaneously	No battery/reverse polarity
Yellow blinks 1X	Not reaching constant voltage setpoint
Yellow blinks 2X	Not reaching 24V within 2 hours
Yellow blinks 3X	Charge current/voltage does not normalize
Yellow blinks 4X	Battery voltage too high (over 32V)
Yellow blinks 5X	Charger over temperature

3		INSTALLATION
	•	Charger should be securely mounted on a flat surface.
	•	The power cord to the IEC 320/C14 connector should be of the appropriate
		gauge to carry a 10A current @ 120VAC, or a 5A current @ 230VAC for
		the cable’s length, to meet the requirements of applicable electrical codes.

• A minimum of 30mm clearance should be provided at each end of the charger for vented models.

• The charger should not be installed in locations which restrict air flow.
