It is also possible to trigger the relay when an alarm condition occurs.
The relay contact is open when the coil is de-energized (NO contact) and will close when the relay is energized.
Factory default setting: the relay is controlled by the state of charge of the battery bank. The relay will be energized
when the state of charge decreases to less than 50% (the discharge oor) and will be de-energized when the battery
has been recharged to 90% state of charge. See section 4.2.2. The relay function can be inverted: de-energized
becomes energized and vice versa. See section 4.2.2.
When the relay is energized, the current drawn by the GP-BMK-50 will increase slightly (see technical data).
4.8 INTERFACE OPTIONS
4.8.1 CUSTOM INTEGRATION (PROGRAMMING REQUIRED)
The Bluetooth Dongle port can be used to read data and change settings. The Bluetooth Dongle protocol is simple
to implement.
Transmitting data to the GP-BMK-50 is not necessary for simple applications, the GP-BMK-50 automatically sends
all readings every second. All the details are explained in this document. Visit gpelectric.com/go-power-connect for

4.9 ADDITIONAL FUNCTIONALITY OF THE GP-BMK-50
In addition to the comprehensive monitoring of the main battery system, the GP-BMK-50 provides a second monitoring
input. This secondary input has three congurable options, described below.
4.9.1 AUXILIARY BATTERY MONITORING
Wiring diagram: see the quick installation guide. Fig 3
This conguration provides basic monitoring of a second battery, displaying its voltage. This is useful for systems
with a separate starter battery.
4.9.2 BATTERY TEMPERATURE MONITORING
Wiring diagram: see the quick installation guide. Fig 4
This temperature sensor is not interchangeable with other temperature sensors, as provided with battery chargers.
The temperature sensor must be connected to the positive pole of the battery bank (one of the two wires of the sensor
doubles as the power supply wire). The temperature can be displayed in degrees Celsius or degrees Fahrenheit,
see section 4.2.5, setting number 67.
The temperature measurement can also be used to adjust battery capacity to temperature, see section 4.2.5, setting
number 68.
The available battery capacity decreases with temperature. Typically, the reduction, compared to the capacity at
20°C, is 18% at O°C and 40% at -20°C.
