3.
Connect the Type 7972-000-04 WSM comms/charger to the WSM6 charger PSU via a
2.1mm power socket. The PSU accepts a standard IEC power lead, and UK, US and
European plugs are supplied with new product.
4.
It is important to observe the charger during the first 10 minutes of operation, as the method
depends on the state of charge of the battery.
a.
If the battery is partially discharged, the red and yellow LEDs will both flash for about 2-
3 minutes, then just the red Fast charge LED will come on, for up to 6 hours.
b.
If the battery is already fully charged, the yellow Trickle charge LED will come on for a
few seconds, go off, then the red fast charge LED will come on for up to one hour.
Finally the red LED will go out and the yellow trickle charge LED will come on again.
c.
If the battery is fully discharged, the red and yellow LEDs will both flash for about 6
minutes, then just the yellow Trickle LED will stay on. Leave on Trickle charge for about
5 minutes, then disconnect, leave for another 5 minutes, then restart. The red Fast
charge LED should now come on, as in the partially discharged case.
d.
If the battery is deeply discharged, the red and yellow LEDS will both flash for about 6
minutes, then just the yellow Trickle LED will stay on. Leave on Trickle charge for about
20 minutes, then disconnect the charger, wait another 5 minutes, then restart. This time
the red and yellow LEDs will both flash for about 2-3 minutes, then just the red Fast
charge LED will stay on for about 6 hours.
5.
When the battery reaches full charge, the red Fast Charge LED will go out and the yellow
Trickle Charge LED will illuminate. The trickle charge may be left connected indefinitely.
6.
Remove the AC power from the Charger to terminate the charging process.
Wait at least 10
minutes before switching the unit on.
7.
Do not re-connect AC power until the battery has been used or left standing for at least 24
hours.
8.
Check that the pressure relief vent is fully home (Red version is sub flush, Gold version is
flush with the end-cap face).
6.4
Corrosion removal
Cases of slight corrosion found on the transponder housing can be treated effectively. Before
proceeding make sure the WSM6 is thoroughly clean and dry.
1.
Clean the corroded area with a degreaser.
2.
Treat with Alocrom for 2 minutes, or until the aluminium goes golden brown.
3.
Wash off with clean fresh water and dry thoroughly.
4.
Make sure the area is completely dry then cover the exposed metal with 2 part epoxy.
