Turning the CL adjustment, which is located on the unit front panel, clockwise lowers the current limit;
turning counterclockwise raises the current limit.
CAUTION: CURRENT LIMIT MUST NOT EXCEED 115%. OF RATED OUTPUT CURRENT.
9.7 FLOAT ADJUSTMENT:
Turning the adjustment, which is located on the front door of the unit, clockwise raises the float voltage.
For adjustable range see Section 2.2.
In the float position, the rectifier will maintain the battery at the voltage level which was preset by the
“Float” potentiometer adjustment and at the same time maintain the load up to the rectifier’s rated output.
Equalize/Select Switch:
This switch is located on the unit front panel. It is a momentary switch. In the up position, the unit can be
selected for either float or equalize operation. In the down position to DCV, DCA, timer mode or Equalize
hours can be selected. Also, switch used to set into calibration modes.
9.8 EQUALIZE ADJUSTMENT:
Turning the adjustment, which is located on the front panel of the unit, clockwise raises the equalize
voltage. For adjustable range see Section 2.2.
In the equalize position, the rectifier will maintain the battery at the voltage level preset by the “Equalize”
potentiometer adjustment and at the same time maintain the load up to the rectifier’s rated output.
10.0 ALARMS AND AUTOMATIC EQUALIZE TIMER
THE UNIT HAS SIX (6) ALARMS FOR CUSTOMER HOOKUP:
1.)
A high & low dc alarms with "led" lights (2) & relays. These alarms are preset at 2.45Vpc high and 2
Vpc low.
2.) A low dc current alarm "led" & relay will indicate if the output current is below the factory preset
level. (1% of DC shunt, 100% rating)
3.) A high voltage shutdown "led" lights if the dc voltage exceeds 2.5 Vpc.. If the voltage remains
above 2.5 Vpc for 20 seconds, the high voltage circuit will trip the ac input breaker turning off the unit.
4.) A summary alarm "led" & relay will indicate if you have low voltage and low current or high voltage
shutdown condition.
CAUTION: THE MAXIMUM CONTACT RATINGS FOR THE ABOVE RELAYS ARE:
MAX. SWITCHED CURRENT- 2A AC OR DC
MAX. SWITCHED VOLTAGE- 150Vdc OR 125Vac
MAX. SWITCHED POWER- 30W OR 62.5Va
5.) AC Power failure "led" & relay.
CHECK THE UNIT SCHEMATIC FOR CUSTOMER ALARM RELAY HOOKUP.
