Batt Temperature Sensor Open / Shorted: If a Bat-

tery Temperature Sensor Cable was installed at start

of charging, but then later found to be open or short

circuited, this error is produced. Inspect Temperature

Device cable for breaks or shorts and correct.

Batt Over-Temperature: If a Battery Temperature

Sensor Cable is installed at start of charging and a

maximum battery temperature is reached, further

charging is then terminated and an error condition is

produced. Check batteries for possible cell damage

and perform a load test on each battery.

Battery Storage Error: While equipment and battery

sits in storage for an excessive amount of time, bat-

teries have depleted. Charging is required immedi-

ately. Connect Charger to A.C. Power to start charg-

ing – error will clear.

Battery Testing Error - Sulphate / Discharged: This

error is only generated by one of two conditions found

during the Pre-Qualification-Test Charge Stage: o

Sulphate: Severely Sulphate battery plates are pre-

venting a charge flow from increasing above a mini-

mum value. Disconnect and reconnect AC Power to

charger to restart this stage. If a second attempt

failed, load test each battery and replace any failed

battery. o Discharged: A severely discharged battery

did not charge up to 1.75Vdc per cell ( for example –

21Vdc for 24V-battery ), within an allotted time span

of approximately 4 to 8 hours. Check for heavy loads

preventing battery from increasing charge and/or de-

fective batteries that will not accept a charge.

Bulk Charge Safety Time Error: Occurs during the

Bulk Charge Stage when its associated safety timer

times out AND the battery voltage was not allowed to

increase above 2.17V/cell. Possible causes include:

use of a battery load that is draining energy from the

battery while the charger is trying to charge that same

battery, aged or unbalanced battery cell conditions,

etc.

Absorption Charge Safety Time Error; Occurs dur-

ing the Absorption Charge Stage when its associated

safety timer times out AND the battery voltage was

dragged below 2.17V/cell. Possible causes include:

use of a heavy battery load that drained energy from

the battery while the charger was trying to charge that

same battery.

Excessive Charge Time Error: Occurs when charg-

ing took too long AND the battery voltage was not al-

lowed to increase above 2.17V/cell. Possible causes

include: use of a battery load that is draining energy

from the battery while the charger is trying to charge

that same battery, aged or unbalanced battery cell

conditions, etc.

Mode Selected Empty: The selected Charge Algo-

rithm, set via the User Selected Switch Setting, is

empty and not a valid setting for charging batteries –

reset the MODE Select switches to a valid value.

Lockout (Inhibit) Enable Defective: If an Equipment

Lockout (Inhibit) Cable is installed and supposed to

be active, but it is not, this error is produced – Check

Inhibit vehicle wiring. If correct, internal inhibit switch

may have been overload – contact factory. Also refer

to the Lockout Inhibit Option Section for External Wir-

ing diagram for this circuit schematic and how it inter-

faces to an equipment's Run-Contactor.

Lockout (Inhibit) Disable Defective: If an Equip-

ment Lockout (Inhibit) Cable is installed and sup-

posed to be deactivated, but was not, this error is pro-

duced – Check Inhibit vehicle wiring. If correct, inter-

nal inhibit switch may have been overload – contact

factory. Also refer to the Lockout Inhibit Option Sec-

tion for External Wiring diagram for this circuit sche-

matic and how it interfaces to an equipment's Run-

Contactor.

Internal Over Temperature: Charger shut down due

to an internal over temperature condition – check fan

operation and remove blockages, if any. Also, remove

any air flow obstructions in and around the immediate

vicinity of the product. Clean/clear away grease,

grime and any debris from product. If this does not

remedy situation, product may have been perma-

nently damaged. Contact the factory or your point of

distribution.
