SHORTED
Short circuit (!) detected at
the output.
-
Check load and cables for any
damages
-
To continue supply process after
error is removed, release clamps
and connect the load again
STANDBY
The device is in sleep mode
(standby).
-
Start the charging / supply process
with choosing ‘START‘.
-
Please consider the configurations
MAN.START or AUTOSTART (see
chapter 5.5.6 Device Menu).
STARTUP
Switch on delay time is
active, the supply starts after
the predefined waiting time.
-
Parameterisation of the switch on
delay time - see chapter 5.5.6
Device Menu
SUPPLY
Operation in SUPPLYMODE
is active (external power
supply)
TRICKLE
The device is in operation
mode trickle charge.
-
Charging process is completed
and battery can be removed.
7. Short Cell Detection - instructions for application
To run the short cell detection failure-free, no relevant load may be connected in parallel to
the charged battery.
Disconnect the battery from the vehicle before starting the short cell check!
For a reliable detection of defective batteries with shorted cells it is absolutely necessary to
pre-set the maximum amp-hour for the battery before the charging operation starts. The
adjusted ampere-hours should not be less than the written value on the battery nameplate
because battery charging stops at the configured value (it is recommended to adjust the
amp-hours 10 to 20% higher). For example with a batteries nominal capacity of 50 Ah the
Q
max
parameter should be pre-set to 60 Ah.
In any case the amp-hour value should be pre-adjusted in the chargers menu (also with
deactivated “CELLCHECK”), because the ampere-hour pre-set limits the charge process
and avoids extreme over-charging. If the “CELLCHECK” is active, the charge process
stops twice for 30 seconds automatically. During that time the charger measures the
battery voltage and an internal algorithm determines if the connected battery is defective.
In case of a battery with shorted cells the charging process stops and “SHORT CELL”
error message is displayed.
