3075 Battery Protector 40A 12V Battery Monitor

Installation and Operating Manual

Please read the Safety Regulations, mounting instructions and operating manual completely prior to starting connection and start-up.
The VOTRONIC Battery Protector 40 had been designed for campers, boats and intervention vehicles and is inserted between battery and consumers. It protects the battery from dangerous total discharge and the consumers from low voltage and overvoltage.
The reset to normal operation is effected automatically, as soon as there is an increase of the voltage to 12.5 V due to battery recovery or short-time charging. Manual cancelling of the disconnection is also possible by means of the function “EMERGENCY ON”.
Remote control of the Battery Protector 40 is possible by means of the terminal “Sensor +” and a simple switch (single-pole ON / OFF). By this, it is becoming an efficient battery main switch.
Also the EMERGENCY-ON function can be remote-controlled.

• Suitable for any type and brand of lead storage battery (Acid, Gel, Dryfit, Heavy Duty, Solar, Fleece, AGM etc.)
• The unit protects the battery from dangerous total discharge.
• It protects the consumers and the equipment from low voltage as well as overvoltage in case of failures.
• Automatic restart after battery recovery (charging).
• High switching current 40 A, short-time overload of 60 A is admissible.
• It can also be used as battery main switch by means of a simple ON / OFF switch (remote control, e. g. from the  living area).
• EMERGENCY-ON function for low battery voltage.
• Display of the switching state being visible from outside.
• Compensation of the voltage loss in the battery cable by separate sensor cable.
• The electronic delay avoids premature reaction, such as in case of voltage drop or if powerful consumers have been connected.
• Suitable for continuous operation (extremely low own consumption 0.002 A (in conformity with EN13796).
• No own electricity consumption in case of disconnection by means of external switch (remote control).

Installation:

1. Chose an installation place being clean and being protected from humidity and dust.
2. The installation place of the unit should be chosen in such way, that the cables of battery and consumers can be as short as possible (losses). Ensure, that the control lever „EMERGENCY“ can always be operated and that it is not blocked by soiling, objects, transported goods etc.
3. The unit is fastened solidly with screws in the casing flanges. The unit can be installed in any position. However, ensure that the terminals and operating elements are easily accessible.
4. Observe to fasten the connection cables in such a way, that neither tensible force, nor force of pressure or bending load are existing.

Connection (Please Observe Connection Plan 1 or 2):
ALWAYS DISCONNECT THE POWER SUPPLY TO THE BATTERY PRIOR TO WORKING ON THE ELECTRIC SYSTEM TO AVOID SHORT-CIRCUITS!
It is recommendable to use connection cables of different colours to avoid defects and malfunctions due to mixed up connections.
Eventual wrong polarization will result in failure of the unit, but it will not be damaged.
If the connection cables for battery and „Load“ are mixed up, the unit will continue working, but the low-voltage disconnection will not be functioning. The battery continues supplying the consumers.
Observe the cable cross-sections and the polarity. Insert the fuses near the battery (protection against cable fire).

Start-up:

If the control lever is blocked (manual blocking, dirt, dust) the electronic system will fail! Now, there is the risk of total discharge of the battery. On the other hand, the battery charge can be utilized completely in an extreme case of emergency (positioning light, lighting etc.).

1. Application as pure protection against total discharge:

HINT:
Fuses should be connected directly at the batteries
(cable protection) with e.g. VOTRONIC Power Fuse Holder.
Disconnection:
a.) Automatically in case of total discharge (low voltage) e. g. below 10.7 V after 10 seconds.
b.) Automatically in case of overvoltage e. g. above 15.5 V after 10 seconds.
c.) Manual disconnection is possible by means of the control lever (main switch function). In this case, restart is also to be effected manually.
Restart:
d.) Automatically after total discharge and battery recovery / battery charging e. g. over 12.5 V
e.) Automatically after overvoltage and decreasing voltage e. g.below 15 V
f.) Manually by actuation of the change lever „EMERGENCY“. If the battery voltage will again be decreasing due to consumer load, the unit will be disconnected again! This procedure should not be repeated unnecessarily often to maintain the longevity of the battery.
2. Additional application as main switch,
Remote control by means of switch ON / OFF in the living area: HINT:
Fuses should be connected directly at the batteries
(cable protection) with e.g. VOTRONIC Power Fuse Holder.
This type of switching allows an effective remote control of the unit by means of a switch being located in the living area.
Since the load of the switch is very low (0.002 A), an execution as microswitch is sufficient.
If the switch is in position “OFF”, the entire electronic system will be completely disconnected. The own electricity consumption being anyhow very low is ceased.
Disconnection:
a.) Automatically, as described below 1. a.) and b.).
b.) Manually, at any time by means of the switch in the living area “OFF”, as described below 1. c.).
Restart:
c.) Automatically, when positioning the switch in the living area to “ON”, as described below d.) and e.).
d.) Manually, at any time by positioning the switch in the living area to “ON”.

EMERGENCY-ON by means of the switch in the living area:
If the Battery Protector 40 has been switched-off duly due to a very low battery voltage, it can be restarted by means of the remote control (emergency function). Set the switch in the living area to position “OFF” and restart after approx. 1 -2 seconds. This can be repeated several times, but the consumers being not necessarily required should be disconnected for relief of the battery to avoid that the unit will be disconnected immediately after that.
If the Battery Protector 40 is disconnected by means of the switch in the living are (main switch function), it can be reactivated nevertheless by means of the control lever “EMERGENCY”. However, in this case, the electronic monitoring system is not active. Therefore, there is the risk of total discharge of the battery. On the other hand, the battery charge can be utilized completely in an extreme case of emergency (positioning lights, lighting etc.).

Safety Regulations:

The Battery Protector 40 has been designed according to the valid safety regulations.

Operating Instructions:

Overvoltage Limitation:
If the voltage rate is e. g. 15.5 V, the supply voltage will be switched-off to protect sensitive consumers. Restart will be effected 10 seconds after the voltage is below e. g. 15.0 V. If such high voltage levels are reached repeatedly, charging controller, battery, charger and battery terminals should be checked.
Battery Life:
Application of the Battery Protector 40 can prolong the battery life considerably. This is obtained by observation of the following general rules:
In contrast to other battery types, batteries on lead basis do not have any harmful memory effect. Consequently: In case of doubt, partially discharged batteries are to be charged fully as soon as possible.
Store only fully charged batteries and recharge them periodically, particularly in case of used (older) batteries and higher temperatures. Sulphation of the battery plates due to total discharge is to be prevented by immediate charging, particularly in case of low and high ambient temperatures.
Observe the instructions and technical leaflets of the battery manufacturers.
Keep batteries cool; choose an appropriate location for installation.
