PROGRAMMING NEXT MAINTENANCE VISIT

(see menu 2):
- Enabling or disabling the service reminder -> Enabled
- Choosing the enable mode in hours or in days -> at 500 hours
- Alarm Service X days or Y hours before enabling -> 50 hours before
indicator 12/02
Multifunction

DISCHARGE INDICATOR (see menu 4):

- Setting parameters according to the characteristics ->Truck delivered with a battery:
of the battery mounted on the truck indicator set according to battery equipment
->Truck delivered without battery:
by default set on the curve Varta – 2.09V - 20% -
0 mn.

6.4 Setting the multifunction indicator after a service visit

The engineer must activate the next visit reminder (see menu 3) and
through the same operation reset the service alarm.

The engineer can open the Bloc Note (see menu 6-6) to store useful information for future interventions.

The engineer can also edit the multifunction indicator parameters (see menu 7).

Menu 3: Display options

This menu helps select and parameterise the information visible on screen:

- The display format for date and time Choose: European(*) / Anglo-Saxon
- The choice of display of the hour meter Choose: Displayed (*) / Non-displayed
- The choice of display of error messages Choose: Enabled(*) / Disabled

- Wheel position screen indicator Choose: Enabled(*) / Disabled

Menu 4: Battery parameters

The discharge indicator must be compulsorily parameterised according to the battery characteristics.

1) CHOICE OF BATTERY TYPE

Various discharge curves are stored in the multifunction indicator memory:
indicator 12/02
Multifunction

1 Battery model: Open lead standard battery (Varta, Fulmen, Oldham, Fenwick) (*)
- Standard FENWICK control for open lead battery.

2 Battery model: Battery PZs (Deta)

- Setting for the Hawker maintenance free batteries (gel).

3 Battery model: Battery with increased capacity (PZs)

- To reserve for the trucks equipped with large capacity battery, with a long discharge duration

4 Battery model: Maintenance free battery (Gel)

- Preferably use the model no. 2 or
- Consult the battery manufacturer to get the characteristics.

2) RESET VOLTAGE/CHARGED BATTERY NO-LOAD VOLTAGE

Possible choices:
2.00 – 2.03 – 2.06 – 2.09 (*) – 2.12 – 2.15 – 2.18 – 2.21 – 2.24 – 2.27 – 2.3 V.

(*): FENWICK standard setting

Remark:
- The battery no-load voltage must be greater than the value selected to unplug
the multifunction indicator.
- The reset voltage can be slightly lowered if the indicator does not reset on
a charged battery.

(*) By default
Section 6
Page 10 Service Training
3) LIFTING CUT

To protect the battery too high discharge, set the residual capacity value (in %) at which the hoist cut is
produced: 20(*) - 25 - 30 - 35 - 40%.

- (*) Standard control for an open lead battery.

- Setting recommended for a maintenance free battery (gel): 30%

TIPS TO ADJUST THE HOIST CUT

After checking the real status of the battery on the cut, gravity and voltage on an open lead battery, voltage
on a gel battery, it is possible to fine-tune the setting according to real use of the battery:

- If the indicator cuts too early, reduce the residual capacity value (E.g.: 25% to 20%)
- If the indicator cuts too late, increase the residual capacity value (E.g.: 25% to 30%)

Remarks: - Minimum gravity, battery 80% discharged; 1.14

- Maximum gravity, battery 100% charged; 1.29 to 1.32 according to models.

4) RESET TIME

After cutting the discharge indicator, it can be reset only after a period of:

indicator 12/02
Multifunction
0(*) - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 minutes.

(*): FENWICK standard setting

MENU 5.1: Programming initialisation

Init. menu 1

Menu 5-2: Initialisation of an hour meter after replacement

On a new multifunction indicator, it is possible to program the hour meter from the old one.

NOTE:
The hour meter can be reinitialised only if there are less 2.9 hours.

Menu 5-3: Point Service Address

This menu shows the Point Service address closest to the truck user:
- Company
- Telephone No.
- Name of person to contact

Menu 5-4: Setting the date

Example: 011202 means 1 December 2002

Menu 5-5: Setting of time

Example: 161202 means 16 hours 12 minutes and 2 seconds
