OPERATION
The PowerTector will guard against excessive battery discharge by disconnecting the
load before the battery voltage drops too low. One second after the battery voltage
drops below the disconnect threshold the alarm output will activate. If the battery
voltage is still below the disconnect threshold after a total of 10s the PowerTector will
disconnect the load from the battery and deactivate the alarm.
The load will remain disconnected until the battery voltage rises above the reconnect
threshold.
The PowerTector will protect the load by disconnecting it if the battery voltage
exceeds 19V on a 12V system or 32V on a 24V system.
ASSEMBLY
1. Select a cool and ventilated position to install the device which is not exposed to
direct sunlight.
2. Mount as close to the battery as possible using a wire of sufficient diameter.
3. Isolate the power to the wiring before commencing installation.
4. Mount using the three mounting holes with screws or bolts.
5. Connect the ‘ground’ terminal.
6. Connect the ‘input positive’ terminal.
7. If required program the unit as described below.
8. Connect the ‘output positive’ once no further programming is required.
9. Connect the alarm and switch if required.
PROGRAMMING
There are 4 settings that can be defined by the user, each setting is in a Program.
Family, as shown in the table below. Changing the setting within a Program Family
does not affect any other Program Family.
Program Family 1: Operating voltage range. P1-P10 (P1 is default).
Program Family 2: Alarm output mode.. P11 (default)—The alarm output will be
constantly active 1s after the voltage drops below the disconnect threshold. It will
deactivate if the voltage rises above the disconnect threshold or 10s after the voltage
drops below the disconnect threshold.
The alarm will activate in pulse mode if the battery voltage rises above 19V for a
12V system or 32V for a 24V system.
P12—The alarm output will be constantly active 1s after the voltage drops below the
disconnect threshold. It will deactivate if the voltage rises above the reconnect
threshold.
The alarm output will not activate if the voltage rises above the over-voltage protection level.
This mode can be used for enabling an external battery charger to replenish the
battery that the PowerTector is protecting.
Program Family 3: Switch terminal mode. P13 (default)—The PowerTector output is
disconnected when the switch terminal is connected to the negative terminal of the
battery.
P14—The PowerTector output is disconnected when the switch terminal is connected
to the positive terminal of the battery.
Program Family 4: Voltage range select. P15 (default)—The unit will automatically
select the voltage range (12V or 24V) each time power is applied.
P16—The unit will operate as a 12V unit only.
P17—The unit will operate as a 24V unit only.
To change a program:
1. Temporarily connect together the ‘input positive’ and the ‘program’ terminal
using the programming lead supplied.
2. The LED will start to flash, each flash indicates the program to be selected.
3. Keep the connection until the LED has flashed the number of times for the desired
program then remove the connection.
4. The LED will then flash the number of times to confirm the selected program.
Alarm** – The use of a relay requires a free wheeling diode to prevent damage – see
application note AN-PT01.
SAFETY
• This PowerTector is for ancillary equipment only. It must not be used to
disconnect equipment that is critical to the safe operation of the vehicle.
• The device must not be exposed to severe mechanical shocks.
• The device must not be exposed to extreme temperature, direct sunlight or
vigorous vibration.
• The device may only be used within a dry environment, such as a vehicle.
• Do not install this device on hot vehicle parts and ensure there is sufficient
space around the device for air circulation and cooling.
• The wiring harness should be protected by fuses.
• Observe the magnitude and polarity of the input/output voltage when
installing, incorrect polarity of the output could damage the circuit.
• Isolate the circuit before you connect or remove the device.
• Ensure that the output of the device is not short-circuited.
• Never open the device casing and never repair it. The device must be
replaced if it is damaged.
INDUCTIVE LOADS
The inductive load rating of this PowerTector is 1mH.
Do not exceed the specified inductive rating.
Inductive equipment includes; motors, pumps, refrigeration, relays, long
cables etc.
Conducted voltage transients must not exceed those specified by ISO7637-
2:2004 Level III
FUSING
The input and ground wiring must be fused appropriately.
For the ground, minimum 500mA to 1A maximum.
