3. OPERATION

3.1 “On/Off/Charger Only Switch”

When switched to "on", the product is fully functional. The inverter will come into operation and the LED "inverter on" will light

up.

An AC voltage connected to the "AC in" terminal will be switched through to the "AC out" terminal, if within specifications. The

inverter will switch off, the "mains on" LED will light up and the charger commences charging. The "bulk", "absorption" or "float"

LED’s will light up, depending on the charger state.

If the voltage at the "AC-in" terminal is rejected, the inverter will switch on.

When the switch is switched to "charger only", only the battery charger of the Quattro will operate (if mains voltage is present).

In this mode input voltage also is switched through to the "AC out" terminal.

NOTE: When only the charger function is required, ensure that the switch is switched to "charger only". This prevents the

inverter from being switched on if the mains voltage is lost, thus preventing your batteries from running flat.

3.2 Remote control

Remote control is possible with a 3-way switch or with a Multi Control panel.

The Multi Control panel has a simple rotary knob with which the maximum current of the AC input can be set: see PowerControl

and PowerAssist in Section 2.

3.3 Equalisation and forced absorption

3.3.1 Equalisation

Traction batteries require regular additional charging. In the equalisation mode, the Quattro will charge with increased voltage

for one hour (1V above the absorption voltage for a 12V battery, 2V for a 24V battery), and with charging current limited to 1/4

of the set value. The “bulk” and “absorption” LED’s flash intermittently.

Equalisation mode supplies a higher charging voltage than most DC consuming

devices can cope with. These devices must be disconnected before additional

charging takes place.

3.3.2 Forced absorption

Under certain circumstances, it can be desirable to charge the battery for a fixed time at absorption voltage level. In Forced

Absorption mode, the Quattro will charge at the normal absorption voltage level during the set maximum absorption time. The

“absorption” LED lights.

3.3.3 Activating equalisation or forced absorption

The Quattro can be put into both these states from the remote panel as well as with the front panel switch, provided that all

switches (front, remote and panel) are set to “on” and no switches are set to “charger only”.

In order to put the Quattro in this state, the procedure below should be followed.

If the switch is not in the required position after following this procedure, it can be switched over quickly once. This will not

change the charging state.

NOTE: Switching from “on” to “charger only” and back, as described below, must be done quickly. The switch must be toggled

such that the intermediate position is 'skipped', as it were. If the switch remains in the “off” position even for a short time, the

device may be turned off. In that case, the procedure must be restarted at step 1. A certain degree of familiarisation is required

when using the front switch on the Compact in particular. When using the remote panel, this is less critical.

Procedure:

- Check whether all switches (i.e. front switch, remote switch or remote panel switch if present) are in the “on” position.

- Activating equalisation or forced absorption is only meaningful if the normal charging cycle is completed (charger is in 'Float').

- To activate:

a. Switch rapidly from “on” to “charger only” and leave the switch in this position for ½ to 2 seconds.

b. Switch rapidly back from “charger only” to “on” and leave the switch in this position for ½ to 2 seconds.

c. Switch once more rapidly from “on” to “charger only” and leave the switch in this position.

- On the Quattro (and, if connected, on the MultiControl panel) the three LED’s “Bulk”, “Absorption” and “Float” will now flash 5 times.

- Subsequently, the LED’s “Bulk”, “Absorption” and “Float” will each light during 2 seconds.

a. If the switch is set to “on” while the “Bulk” LED lights, the charger will switch to equalisation.

b. If the switch is set to “on” while the “Absorption” LED lights, the charger will switch to forced absorption.

c. If the switch is set to “on” after the three LED sequence has finished, the charger will switch to “Float”.

d. If the switch has not been moved, the Quattro’s will remain in ‘charger only’ mode and switch to “Float”.
