1411. Charging power supplyThe battery charger is suitable foran input voltage of between 100Vand 240V. The output voltage is 33V=. The charging current is 1 A.There are different diagnostic codesif the lift requires chargeCode 1 and 7: When the battery voltage is very low (maybe down to10%capacity left in batteries), this fault code will appear. When thelift docks on to charge contacts, the lift will not drive off the contacts.1 will flash. Lift will only drive off if battery voltage has recoveredapproximately three quarter capacity. Another way of driving off thecontacts is if lift is powered “off” then back “on” but as soon as liftdocks on contacts, process will repeat again. This fault code is linkedto fault code 7 but the code 7 is not usually seen as code 1 takespriority.Code r: This fault will occur when the lift is charging. If the powersupply is disconnected while the lift is charging, the r code will display.A fault with the 33V power supply where the power supply cannotsupply current to charge the batteries will also show this code.Code U: This fault occurs when the lift has fully charged the batteriesand is in float mode. When the 33V power supply is disconnected, theU code will display.Code E: This fault appears if the batteries are low. The main relay onthe board is rated for 24VDC operation so the low voltage will give afalse fault condition.
