Trouble-Shooting - LAMAR BETA D-50 Operating Manual

6. TROUBLE-SHOOTING

Problem Possible Cause
A. Unit will not turn on The AC power is not
connected to unit
AC line fuse is blown.
May be due to incorrect
AC line voltage setting.
B. Unit turns on but will Timer is set to zero time,
not start (timing) or incorrectly to seconds
or low decimal unit.
C. Battery voltage Voltage sensing lead(s)
reading erratic or at battery connector
not reading loose or broken
D. Discharge test will Battery is not sufficiently
not start charged to start the test
Timer is set to zero time,
or incorrectly to seconds
or low decimal unit.
Cutoff voltage set higher
than the actual battery
voltage
The lead-acid battery is
sulfated and will not
support a load
E. Battery sufficiently High resistance or open
charged but circuit in DC cable at
discharge test fails Elcon connector, in the
immediately as cable itself, or in the
discharge current is voltage sensing leads
increased attached to connector
The lead-acid battery is
sulfated
The nickel-cadmium
battery inter-cell
connectors are loose or
contaminated causing
high resistance

6. TROUBLE-SHOOTING
Corrective Action
Check AC line with voltmeter
Ensure correct AC line voltage
setting on back of unit. (see
section 2.1)
Replace AC line fuse located
on the lower right hand side on
the rear of the unit (see
section 5.6)
Increase the timer setting (see
section 4.4)
Replace or secure leads with
both AC voltage and battery
disconnected (see section 5.6)
Recharge battery before
retrying discharge test
Increase the timer setting (see
section 4.4)
Reset the cutoff voltage to a
lower voltage (see section 4.6)
or recharge battery.
Recondition or reject the
battery
Inspect and measure
resistance in DC cable and
connector. If high or
intermittent high resistance,
the cable needs to be replaced
Check all terminals. Set a low
discharge current and look for
arcing or heat generation.
Check all terminals and inter-
cell connectors. Set a low
discharge current and look for
arcing or heat generation.
