Code Issue

XFMR The control transformer primary is mis-wired.

Solution

Contact your dealer’s Qualified Service Technician to correct the control transformer primary wiring.

PWRA The control board has AC power available, but the charger is unable to produce DC output power.

Contact your dealer’s Qualified Service Technician.

The issue likely lies in the charger AC path (AC contactor, AC fuses, etc.).

6. DOOR WITH SWITCHES AND AC CONTACTOR (OPTIONAL)

Chargers that were purchased with the AC contactor option are equipped with internal lockout switches on the front door. When the door is opened, the switches are opened, and AC control power is removed from the controller and the AC contactor, de-energizing both. This removes AC power from some internal components of the charger. AC POWER IS STILL ENERGIZED AT THE AC INPUT CONNECTIONS, AC FUSES AND

CONTROL TRANSFORMER INSIDE THE CHARGER.

The controller will also open the AC contactor when a charge cycle is not active. This both conserves electricity and extends the lifetime of charger components, which reduces operating costs.

7. DC OUTPUT

The DC output cable includes a commonly-used connector. The polarity of the charger connector 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 if the polarity is reversed. The DC output fuse, F3 (single-phase), is a fast-acting fuse used to protect the SCRs.

USE ONLY THE CORRECT SIZE IDENTICAL TYPE REPLACEMENT FUSES. FUSES ARE AVAILABLE

FROM YOUR DEALER’S QUALIFIED SERVICE TECHNICIAN.

This charger is capable of charging batteries with cell counts and DC voltages up to the maximums listed on the ratings label, as configured at time of charger order. Do NOT charge batteries with cell counts and DC voltages greater than those listed on the charger ratings label.

8. PROPER CARE OF DEEP-CYCLE MOTIVE POWER BATTERIES

Motive power batteries are subjected to severe deep-cycle duty on a daily basis. Although these batteries are designed to withstand such duty, the following precautions must be observed to obtain good performance and maximum cycle life.

CAUTION: ALWAYS WEAR PROTECTIVE EYE SHIELDS AND CLOTHING WHEN WORKING WITH

BATTERIES. BATTERIES CONTAIN ACIDS WHICH CAN CAUSE BODILY HARM. DO NOT PUT

WRENCHES OR OTHER METAL OBJECTS ACROSS THE BATTERY TERMINAL OR BATTERY TOP.

ARCING OR EXPLOSION OF THE BATTERY CAN RESULT.

1. When installing new batteries, be sure the polarity of each battery and the overall battery pack is correct.

Otherwise, battery and/or charger damage can result.

2. New batteries should be given a full charge before their first use because it is difficult to know how long the batteries have been stored.

3. New batteries and older batteries that have been in storage are not capable of their rated output until they have been discharged and charged a number of times.

4. DO NOT EXCESSIVELY DISCHARGE THE BATTERIES. Excessive discharge can cause polarity reversal of individual cells resulting in complete failure shortly thereafter.

5. Maintain the proper electrolyte level of wet (flooded) batteries by adding water when necessary. Distilled or deionized water is best for battery life. Never allow the electrolyte level to fall below the top of the battery plates. Electrolyte levels lower during discharge and rise during charge. Therefore, to prevent the overflow of electrolyte when charging, it is mandatory that water be added to cells AFTER they have been www.douglasbattery.com 13 of 30 User’s Manual
