MCB controller has two independent communications lines. One of the lines is dedicated to remote control panels, another one – to BMS network. The
latter is galvanically insulated. Communication protocol – Modbus RTU.
Based on manufacturer set parameters
› Modbus address – 1;
› Communications Line speed – 19200;
› Data package structure – E,8,1 (communications line parity: even).
Communications lines are configured in the service environment window SERVICE › COMMUNICATION.
If necessary, a complete description of miniMCB func-
tions can be downloaded from www.salda.lt.
FACTOR“ to “1”.
The pressure sensor of the heat exchanger can be connected to the third 0-10 VDC input.
For each input, the sensor voltage interval (0-10 V, 1-10 V, 0-5 V, 0.6-2.7 V, 0-3.3 V) and the minimum and maximum values are indicated for each
input.
Types of temperature sensors:
› NONE – sensor is not connected;
› REMOTE – remote; sensor temperature can be indicated via Modbus;
› NTC 10K 3977 – NTC sensor is connected.
› NTC sensor with a non-standard beta (2750 – 5000). After changing the beta coefficient, it is necessary to save and restart.
In this system every type of sensors and possible actions in case of failure are indicated.
› Do nothing – only warning is displayed;
› Shut down the system – system is stopped, alarm is displayed;
› Emergency mode – operation is continued, but sensor-dependent functions are switched off, warning is displayed.
Sensors are configured in the service environment window SERVICE › SENSORS.
