2. Installation
2.1 General principle
1）Make appropriate installation holes on the control box, ( size: 179（±1）mm ×113（±1）
mm)
2）Install the GM9907-L5 into a control box
3）Remove the fixing plates on both sides of GM9907-L5, fix it with the fixing plates and
lock them with M3*10 screws.
2.2 Load Cell Connection
GM 9907- L 5 bulk scale controller can connect resistance strain bridge sensor.
When chose the six-wired load cells, must bridge the SN+ with EX+ and bridge the SN-
with EX-
EX+:Excitation+ EX-:Excitation- SN+:Sense+ SN-:Sense- SIG+:Signal+ SIG-:Signal-
2.3 I/O Function Connection
GM 9907- L 5 bulk scale controller controls 28 lines I/O (12 input and 16 output).
It uses optoelectronic isolation technology to transfer data. The I/O signal input is low level
effective, and the output is open-collector mode. The driving current can reach 500mA and
the full load current is up to 3A, and Terminal connection is shown as below:

I/O Function output connection diagram
I/O Function value of GM9 9 0 7-L5 is user-defined to facilitate wiring and some
special applications. Please refer to section 4.5
2.4 Power Supply Connection
GM9907- L 5 bulk scale controller use 24V DC power supply. The connection is
shown in the figure below：
Power terminal diagram
24V+ connect DC+，24V-connect DC-.
Note：this product use 24V DC power
supply，use 220V AC power supply will
permanently damage the controller and
cause danger.
