2.0INTRODUCTION
The GNB SCR100 battery chargers are convection cooled, solid state, micro-processor controlled SCR regulated chargers designed to make battery charging simple. They are factory set to charge sealed lead-acid batteries but it may be configured by a GNB service representative to charge flooded lead-acid batteries.
The charger has a comprehensive self-checking diagnostic program to control all charger functions, monitor the quality of charge and check its own safety conditions. Large easy to read LEDs, three button keypad and LED display report on charger and battery status.
3.0RECEIVING CHARGER
Examine the charger thoroughly before using, to make sure that no parts have been loosened or damaged during shipment. Check the contents of the package against the delivery slip before disposing of the shipping package. If any shipping damage or partial loss is found, file a claim with the carrier without delay and take any necessary steps to protect your rights. Before installing check that the charger nameplate data corresponds to the packing slip and to the model specified on the original sales order.
The SCR100 chargers are delivered on skids for easy handling using a fork lift truck.
4.0LOCATION AND INSTALLATION OF
CHARGER
Proper installation is important in order to achieve good charger performance and long troublefree operation and to prevent damage to the charger and batteries. The charger should be located in a clean, cool, normal ambient room temperature (between +45°F/7.2°C and 90°F/32.2°C) dry and well ventilated area. In order to permit free air flow for convection cooling allow four inches minimum between the charger and any wall, six inches from other equipment, and never store anything beneath and on top of the charger.
4.1STACKING
When stacking chargers on top of each other, ensure that cabinets are bolted together using properly sized black #1/4-20 UNC hardware provided in all four corners on top cover. The floor mounting must be done with #3/8-16 UNC bolts (steel rack) or #3/8 lag screws and anchors (concrete floor). All charger models with a Z, SCR100-XX-XXXT1Z OR SCR100-XX-XXXS1Z, can be stacked to a maximum of three high.
WARNING: THE ABOVE PROCEDURES MUST BE FOLLOWED EXACTLY TO AVOID INJURY OR RISK OF ELECTRIC SHOCK.
WARNING: TO REDUCE THE RISK OF FIRE, INSTALL BATTERY CHARGER ON A FLOOR OF NON-COMBUSTIBLE MATERIAL SUCH AS
STONE, BRICK, CONCRETE OR METAL. IF THIS IS NOT AVAILABLE, A FLOOR PLATE OF AT LEAST 1.43mm GALVANIZED OR 1.6mm UNCOATED STEEL EXTENDED AT LEAST 150mm BEYOND THE EQUIPMENT ON ALL SIDES MUST BE INSTALLED.
5.0AC ELECTRICAL SUPPLY
The charger must be connected to either a single phase, or three phase 50 or 60 Hertz (± 2%) AC power source. The following options are available:
TABLE 1 – INPUT VOLTAGE CHOICES
Single phase |
Three phase |
|
a) 120/208/240VAC, 60Hz |
e) 208/240/480VAC, 60Hz |
|
b) 208/240/480VAC, 60Hz |
f) 480VAC, 60Hz |
|
c) 600VAC, 60Hz |
g) |
600VAC, 60Hz |
d) 240VAC, 50Hz |
h) |
380/415VAC, 50Hz |
Only the AC input wire configuration for multi-input chargers can be changed. Follow Figure 1 (page 4) for single phase input or Figure 2 and Figure 3 (pages 5-6) for three phase input transformers. This change should be done by a qualified electrical contractor.
5.1AC FUSE MOUNTING
The charger comes with a fuseblock rated big enough to accommodate the highest possible current and voltage for that particular model. Proper fuse ratings can be found in Table 2 and Table 3(see pages 9-12) for AC input fuses (F1, F2 in case of a single phase input or F1, F2, F3 in case of a three phase input). Fuses with an ampere rating of 30A or less are smaller and need fuse reducers when placed in a 60A fuseblock.
5.2INPUT VOLTAGE CHANGE
Before proceeding check which transformer tap configuration you have. When changing the taps on the input side between 1) 120, 208, 240 VAC or 2) 208, 240, 480 VAC (single phase input), be sure to change the wires and/or jumpers according to Figure 1 (page 4). Once finished, refer to Table 2 (pages 9-10) for the correct size of AC input fuses. Similarly when changing input voltage between 1) 208, 240, 480 VAC or 2) 380, 415VAC (three phase input) follow the schematics on Figure 2 or Figure 3 (pages 5-6) whichever is applicable. Following that, check Table 3 (pages 11-12) for the correct size of AC input fuses. Figure 3 (page 6) applies to 12 cell 475, 600, 750, 865 Ah; 18 cell 475, 600, 750, 865, 965, 1050 Ah; and 24 cell 475, 600, 750, 865Ah chargers only.
NOTE: Upon completion and proper verification of the input voltage configuration change, markings on the door label and the unit nameplate must be revised (crossing out factory set markings); re-mark the label with a permanent marker to reflect new input voltage configuration and fuse size.

AC VOLTAGE CONNECTIONS |
6.0 |
DC OUTPUT |
To connect the input AC voltage, route the AC conduit through the knockout hole provided. Continue the AC wiring to fuseholder terminals L1 (N) and L2 (L) (single phase input) or L1, L2, and L3 (three phase input), ensuring that the AC source phases match the phase rotation on the AC input. For proper connection, torque the screws to approximately 25 inch-pounds.
5.4GROUND CONNECTION
It is a requirement to ground the chassis while the charger is connected to AC power. The charger comes with a ground lug attached to the stud, clearly marked on the chassis. To ensure good continuity keep the contact area clean. The stud is designed for a 3/16” hardware. See gounding method shown below (Figure 4.).
WARNING: DO NOT OPERATE THE UNIT WITHOUT PROPER GROUNDING. IMPROPER GROUNDING CAN RESULT IN THE RISK OF AN ELECTRIC SHOCK.
CAUTION: USE MINIMUM 75°C WIRING. FOR SUPPLY CONNECTIONS, GROUND CHARGER PROPERLY USING GROUNDING STUD (GND) PROVIDED. USE COPPER-CLAD ALUMINUM, ALUMINUM OR COPPER CONDUCTORS ONLY.
After electrical connection is completed, the charger is ready for operation.
NOTE: The following applies to three phase chargers only: if the charger indicates “FAC” or “F3” upon startup, it means that there is a low or high AC voltage (+35%) or AC phase missing. Refer to the Troubleshooting section for more details.
The DC charging cable has a commonly used battery plug or receptacle. The polarity of the charger plug must be the same as the battery connector. The BLACK DC cable must be connected to the battery negative (-), and the RED DC cable must be connected to the battery positive (+). The charger will not operate in a reversed polarity condition.
The DC output fuse is a "fast-acting" fuse used to protect the power semiconductors of a charger.
NOTE: Use only identical replacement fuses obtainable from your GNB service representative

7.0APPLICATION
The charger will automatically charge a battery per the Ah rating set at the factory. The charger can be re-set for anywhere between 65% to 200% of the nameplate Ah rating. Ensure that battery and charger are matched. Keep in mind if the charger is set for more than 100% of Ah of the charger rating the charging time will increase proportionately (up to 16 hours). For battery sizes not listed, contact your local GNB service representative.
7.1FAULT AND DISPLAY CODES
Refer to Appendix A (on page 20) for a complete list of codes.
7.2OPTIONS
7.2.1JIC SWITCH ASSEMBLY
All SCR100 battery chargers can come with a factory installed fused JIC switch assembly option for extra protection of the operator. In the "OFF" position, the door can be opened but only AC power at the input of the switch is present while everything downstream is dead. In the "ON" position, AC power is supplied to the charger but the door cannot be opened. See applicable drawing 4770-65-73041-05, 4770-65-73041-15 or 4770-65- 73041-17 for electrical schematic (Appendix B, pages 21-31). NOTE: Only HRCI-R type fuses (ECSR or equivalent) with the notched ferrule at one end can be used. A JIC type charger can only be factory installed and is available in a “B”, “C” or “D” size cabinet.
7.2.2BATTERY WATERING OPERATION AND END OF CHARGE
The SCR100 battery charger has an available watering control and end of charge option, in the form of a relay contact at terminals TB10-1 to TB10-2 (supplied for customer connection). The relay closes thirty minutes after the charger reaches gassing voltage. It remains closed for approximately ten minutes.
NOTE:These options require different control cards per drawing 4120-65-68650-05 (see Appendix B, pages 2131).
RELAY CONTACT RATINGS:
-AC: 125V 0.6A 1.0PF maximum
-DC: 30V 2A resistive maximum
7.2.3REMOTE STOP / EQUALIZE
The SCR100 battery charger can come with a factory installed Remote Stop / Equalize assembly option (partnumber V16-31365-50) in case the charger is out of reach for the operator. The end user will have to install two separate push buttons to the appropriate terminals on the Remote Stop / Equalize circuit board (see schematic 4120-66-68650-50) and locate them to a
convenient location for use. When installing the push buttons ensure that there are no corrosive fumes deteriorating the contacts. The Remote Stop / Equalize option is available for “Z” model chargers “B” and “C” cabinets, 6 – 36 cells only. For non “Z” models contact your local GNB service representative.
