DESCRIPTION OF THE BATTERY CONDITION INDICATORS
The battery condition indicators will give an indication of the state of charge of the batteries. The battery condition monitor will retain the state-of-charge even if
the key has been turned off. The state-of-charge indication is reset to full charge when the batteries have been recharged. It is also possible to choose between
two different low voltage thresholds depending on whether maintenance free or standard batteries are being used (have qualified service engineer perform
this selection). NOTE: The following percentages are based on useable battery capacity not total battery capacity. Therefore, 100% discharge = 80% of total
battery capacity for standard wet cell batteries or 70% of total battery capacity for maintenance free batteries.
Green Indicator = full charge down to 50% discharge
Green & Yellow Indicator = 50% discharge down to 75% discharge
Yellow Indicator = 75% discharge down to 90% discharge
Yellow & Red Indicator = 90% discharge down to 95% discharge
Red Indicator = 95% discharge down to 99% discharge
Flashing Red Indicator = 100% discharge - scrub system will automatically shut down
DESCRIPTION OF HOURMETER / STATUS DISPLAY
The 5 character display in the upper right corner of the control panel is primarily used as a display for the hourmeter function. This display is also used to display
the following information depending upon which mode the control is in:
•
Error codes*
•
Brush pressure adjustment settings for normal and heavy scrub mode (fixed and adjustable)*
•
Display of control system default parameters*
•
Recovery tank FULL indicator*
* NOTE: Have a qualified service engineer reference the Service Manual for explanations about the error code descriptions and scrub system control default
parameter changes. A brief description of error codes can be found at the back of this manual.
Emergency Stop Switch / Battery Disconnect (12): This will remove all power from the machine.
INSTALL THE BATTERIES
WARNING !
Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin or
eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery caps. This gas can be ignited by
any electrical arc, spark or flame.
When Servicing Batteries...
*
Remove all jewelry.
*
Do not smoke.
*
Wear safety glasses, a rubber apron and rubber gloves.
*
Work in a well-ventilated area.
*
Do not allow tools to touch more than one battery terminal at a time.
CAUTION !
Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Batteries
should be installed by Nilfisk-Advance or by a qualified electrician.
1
Turn the Key Switch (33) off (O) and remove the key. Then swing open the Battery Compartment Cover (15).
2
Using (2) people and an appropriate lifting strap, carefully lift the batteries into the compartment tray exactly as shown. Use decal 56016345 battery cable
layout.
3
See Figure 1. Install battery cables as shown and tighten the nuts on the battery terminals.
4
Install the battery boots and secure tightly to the battery cables with the supplied tie straps.
5
Connect the battery pack connector to the machine connector and close the battery compartment cover.
