The base monitor unit have two relay output for alarm, the connect pin for relay please refer to
chart 3.2.
In setting menu, choose this item, and press to enter the alarm
setting.
The monitor will show:
Monitor can set two alarm output values:
Alarm threshold temperature: for notes onsite person the
temperature change
Trigger threshold temperature: can connect breaker or other
Actuator to forced shutdown circuit, prevent over-temperature damage
Note: Trigger threshold value should be higher than alarm threshold value
After set, press to save and escape the local time setting
6.1.3.- Comm setting
Base monitor unit can be connected to a P.C. With thissystem we
can get all the parameters in one central point of reading. It hasa
serial RS-485 port. If we connect more than one device to the same
communication line (RS-485), we have to assign to each of them a
different code or direction (from 1 to 247), since the P.C. needs the
identification of every measuring point.
Line one means the Communication address, the set value from 1~247
Line two means the “BAUD”, the set value from 4800~38400
