Chapter ii Installation and Wiring
2.1 Connecting Power cables to the controller
The packaging controller uses 220V, 50Hz AC power supply
with protective ground.The connection is as shown below:
2.2 Sensor Connection
Gmt-h1 mold block shall be externally connected with resistance
strain bridge sensor, and the sensor shall be connected to the module as
shown below.
When a four-wire sensor is selected, the SN+ and EX+ of the
module must be short-circuited, and the SN- and EX- must be
short-circuited.Each port of the sensor connection terminal is assigned to:

Matters needing attention:
1.
Because the sensor output signal is more sensitive to electronic noise
analog signal, so sensor wiring should be shielded cable, and laid separately
with other cables, especially away from the AC power supply;
2.
For the transmission distance is short and the temperature change is not
large occasions or precision requirements are not high occasions can choose
