Wiring

1) The output of the mainboard engineering

load control interface is a strong electric

signal, so it must be powered off.

2) The engineering load control interface is only

used as a signal output. The total output

current of the mainboard cannot exceed

2.5A, otherwise it will cause overload and

damage the machine.

3) Please connect the engineering load in strict

accordance with the wiring diagram. The

excessive load power needs to be controlled

by the AC contactor. AHS and K_heater2

must pass the AC CONTACTOR control.

4) The connection and installation of external

engineering loads must be well protected,

such as earthed effectively, air switch and

residual current operated circuit-breakers.

The installation of engineering load shall be

installed in strict accordance with the

instruction manual of the load and control

components and local regulations.

"CN400" terminal is used for remote ON-OFF

switch; when using this function, this interface

is connected to external control switch,

remove the short connector of JR400 when

you use the "ON-OFF" function.

The control logic is as follows:

Remote switch short circuit: the machine is

controlled as normal.

Remote switch off: the machine enters remote

control.

3. Remote switch function

4. DIP SWITCH FUNCTION

5. Battery installation

1. The battery is placed in the accessory bag and

needs to be installed in the wired controller on

site.

2. Please remove the wired controller, place the

battery in the unit and ensure the positive side

of the battery is in accordance with the polarity

markings.

3. Set the correct time before operating. Battery

in the wired controller can maintain the correct

time during a power failure. When the power is

restored and the displayed time is not correct,

replace the battery.
