3. Operation
3.1 “On / stand by / charger only” switch
When the switch is switched to “on”, full device operation is initiated.
The inverter will turn on, and the “inverter on” LED will light.
120VAC applied to L1-1 or L1-2 (see fig 1) will be switched through to the AC output connection. The inverter is switched off,
the “mains on” LED will light and charger operation will be initiated. Depending on the applicable charging mode at that time,
the “bulk”, “absorption” or “float” LED will light.
If the voltage on both AC-in connections is rejected, the inverter will be switched on.
If the switch is set to “charger only”, the inverter will not turn on in the event of AC supply failure. Thus the batteries will not be
discharged by the inverter.
3.2 Remote control
Remote control is possible with a simple 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-in-2 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). The charging current is then limited to
1/4 of the set value. The “bulk” and “absorption” LEDs 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 Compact can be put into both these states from the remote panel as well as with the front panel switch, provided that all
switches (on the unit, and possibly a remote switch or the switch on the Multi Control panel) are set to “on”.
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:
1. Check whether all switches (i.e. front switch, remote switch or remote panel switch if present) are in the “on” position.
2. Activating equalisation or forced absorption is only meaningful if the normal charging cycle is completed (charger is in 'Float').
3. 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.
4. On the MultiPlus (and, if connected, on the MultiControl panel) the three LEDs “Bulk”, “Absorption” and “Float” will now flash 5 times.
5. Subsequently, the LEDs “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 is has not been moved, the MultiPlus will remain in ‘charger only’ mode and switch to “Float”.
