This warranty excludes replacement of fuses, triac, calibration, contact points and damage to the module
from the use of improper styles of fuses. The maximum allowable fuse rating is 15 amps. Lower ratings
may be used for improved protection.
SAFETY
Our products have been designed to be safe and simple to operate. As with any electronic equipment, you must
observe standard safety procedures to protect both yourself and the equipment.
Service and installation of this equipment should only be performed by qualified service personnel familiar
with high voltage electrical circuits.
All national and local electrical codes must be followed when connecting this equipment.
Only persons with knowledge of the system's operation and capabilities should operate the system.
Read all of these instructions before connecting power and turning on the system.
Unless specifically explained in this manual or directed by us, do not attempt to repair the system yourself.
Doing so could result in damage to the system, or serious personal injury.
Do not apply voltage to a terminal that exceeds the range specified for that terminal.
Do not connect thermocouples to any live areas of the heaters. Lock out and tag the controller and mold and
make sure there is electrical insulation between the thermocouple and any live areas.
Do not operate this product from a power source that applies more than the voltages specified.
Do not operate this product with covers or panels removed. All unused slots of a main frame must be
covered with the appropriately sized blank panels.
Do not operate this product when wet.
Do not operate this product in an explosive atmosphere.
CAUTIONS
When turning on the system, you should turn on all circuit breakers before power on the HMI. You may
experience communication issues if you do not obey this sequence.
After turning on the system, you should make sure that fans are running.
Never allow the fan outlets on the unit become blocked, This is where the system's cooling airflow exits. If
this area of the mainframe becomes cluttered and insufficient airflow or the system maybe damaged.
When switching off the system, you must wait 30 seconds before switching on. You may experience
communication issues if you do not wait the required 30 seconds.

Chapter 1 Introduction
1.1 M20 Series Mainframe Configurations
The M20 controller is made up of 4 different models of mainframes which change based on the number
of zones required. These are referred to as M20-XS, M20-S, M20-M, and M20-L.
All of the mainframes employ the same temperature control module M20-M2, and the same sequence
valve gate control module M20-V2.
Access to all users’ serviceable parts, including fuses, are done through the front of the controller by
loosening the upper and lower screws on each heat sink and using the attached tool or screw driver to
lever the module out.
The connectors for the mold-power and thermocouple cables, and the connectors for valve gate control
cables, are located at the rear of the mainframe.
Typical M20 Mainframes
M20-XS M20-S M20-M M20-L
1.2 Control Modules
M20-M2 temperature control module come standard with two zones at 15amps per zone.
M20-V2 sequence valve gate control module can control six valve gates each module.
The modules are fully interchangeable across all mainframe designs. The externally mounted heat sink
and integrated design reduce maintenance cost and downtime.

Chapter 3 Connecting the System to the Mold
3.1 Prior to Start Up
●Check that the system is completely disconnected from the power source.
●Clean up any water, oil, dirt, cleaning fluids etc. that may have spilled during a mold change or since
the last production run.
●Check all of the cable connections between the system and the mold (if required). Make sure all of the
cables are free from wear or damage.
●Check that the earth/ground connection is in good condition. Verify the system and the mold have the
same ground reference.
●Check if the wiring mode on mainframe is same as on mold.
●Confirm that the sequence valve gate control output meets the requirement of the valve.
●Confirm that the sequence trigger signal meets the requirement of the controller.
3.2 Verifying the Connection
1. Connect the thermocouple and mold power cables (if required).
2. Connect the sequence trigger signal cable and output cable (if required).
3. Using an Ohmmeter, touch one test lead to the mold and the other to the mold ground terminal on the
system. Resistance must be less than 1Ω.
4. Check all the circuit breakers and make sure they are in the OFF position prior to connection of the
controller to the power source.
3.3 Startup Procedure Checklist
1. Connect mold power & thermocouple cables, sequence control cables between the mold and
controller (if required).
2. Connect the controller to the power source.
3. Switch the circuit breakers ON.
4. Turn on the HMI, then select the language.
5. Log in the system (if required).
6. Load a mold setup (if required).
7. Checking the mold setup zone by zone on HMI.
8. Correct any faults found during diagnostics.
9. Touch “Run” to start the system.
10. Check that the controller is functioning correctly.
IMPORTANT!
When switching off the system, you must wait 30 seconds before switching on. You may experience

4.2 USB Port
The USB port on the M20 series is intended to be used to copy pattern (mold) setup files to and from the
system. The screen for importing or exporting mold setups is displayed in the Group Setup Screen.
These mold setup files can be copied to other M20 controllers that support the same file type.
The USB port is also be used to export the historical data record (in csv format) from the system. The
screen for exporting data record is displayed in the History Data Curve Screen.
CAUTION!
Never power on with a device in the USB port.
Never connect a powered hub or other device to the USB port.
Removing the USB disk from the system during a read or write operation could cause data corruption
to the USB disk contents that could result in bad files or the entire drive from being usable.
The following warnings and restrictions should be observed when using the USB port:
Only supports USB disks that use a File Allocation Table (FAT or FAT32) format.
Only supports USB versions 2.0 and 1.1.
Use an empty USB disk or one that contain as few files as possible.

In order to avoid accidents happened, and protect the system data, different level operators have different
authorities.
To achieve the corresponding authority, the operator should login the system by his or her user name and
password before operation.
And he or she should logout the system after finishing operations, in order to avoid other people
mis-operate the controller by his or her name.
In the absence of user login status, the main interface displays [Login]. Touch it to open
the Login screen, select the corresponding user name and input password to login the system.
In the status of the user login, the main interface shows [Logout]. Touch it and the system
opens a dialog box to confirm your operation. You can click [Yes] to logout the system.
