TSI Instruments Flowmaster 250DL User Manual

!
This new range of battery chargers utilises the latest
computer controlled technology designed to give
greater charging control of Lead Acid batteries, with
increased product reliability.
What follows is the procedure for the correct operation
of the battery charger:
1) Make sure the charger is unplugged.
2) Connect the battery as shown in Fig. 5.1.
3) Plug the charger in and switch ON.
4) During start up the charger will determine battery
status and depending on the result will switch to
either bulk charge mode (red indicator ON) or oat
charge mode (green indicator ON). Note, when
the charger enters oat charge mode the battery is
100% fully charged.
5) If neither of the indicators illuminate then unplug
the charger, check the fuse in the plug, replace if
necessary, plug back in and switch ON.

6.1 OVERVIEW
6.2 FEATURES
6.3 OPERATION
Short Circuit Protection – Prevents damage to
the charger if the dc output is short circuited, visual
indication is by alternate ashing red and green
indicators.
Reverse Polarity Protection – Prevents damage to
the charger if the battery is accidentally connected in
reverse, visual indication is by a continuous ashing red
indicator.
High Temperature Protection – If the internal
case temperature rises above a pre-determined level
the system is designed to automatically shut down the
charging current, thus reducing the case temperature. As
the temperature reduces the charger will automatically
turn up to the maximum charging current available.
Simultaneous ashing of the red and green indicators
will visually indicate high case temperatures.
Soft Start – On power up the system will enter a
“soft start” mode. This facility checks for possible faults
i.e. reverse battery connection, short circuit, etc. before
offering maximum charge current.
Constant Current Bulk Charge and 3 Stage
Charging – Provides the fastest possible way to
recharge a SLA battery without overcharging.
Constant Voltage Float – Compensates for self
discharge, holding the battery at peak charge, ready for
use. The battery can be left on charge until required
without fear of overcharging.
Proportional Charging – Automatically,
proportionally adjusts the second (constant voltage)
stage length of charge based on the time taken to
carry out the rst (constant current) stage. This facility
allows optimal charging by eliminating overcharging and
compromise of the xed charge timers.
First Stage – constant current (CC) mode. Visual
indication: Red LED ON, Green LED off.
Second Stage – constant voltage (CV) mode. Visual
indication: As above.
Third Stage – oat charge mode. The battery will be
maintained 100% charged. Visual indication: Green LED
ON, Red LED off.
Note: On power up the charger will appear to be in
“oat” mode for a short period of time. This is to
complete all checks as described in feature “soft start”.
