12(28)
2. Structure Characteristics and Working Principle
2.1 Working Principle
Picture 2-1: Working principle
In the drying process, hot air with constant temperature is blown by the drying
blower 2 of SHD into the drying hopper 7 to dry the materials. Moisture will be
separated out and taken away by hot air, thus to gain a satisfied drying effect.
Air blown out of blower via hot air pipe 4 became high temperature drying air after
being heated. Through shade separator 5 and screen protector 6, hot air can be
equably dispersed to the material in storage tank (see picture). Hot air recycler is
optional so the air entered drying hopper 7 after being filtered by return air will get
into the drying blower 2 to form a closed loop circle, which saves electricity.

3. Installation and Debugging
Notes for Installation and Positioning：
1) Machine just can be mounted in vertical position. Make sure there’s no
pipe, fixed structure or other objects above the installing location and
around the machine which may block machine’s installation, hit objects or
injure human person.
2) In order to maintain convenient operation, it’s suggested to keep 1m
space around the machine. Please keep at least 2m distance between the
device and the inflammable goods.
3) This series of models only could be applied in working environment with
good ventilation.
3.1 Direct Installation
Picture 3-1: Direct installation
Direct installation type is to mount the hopper dryer directly on the molding
machine via a standard base. SHD-12~300 is suitable for this mounting method
as well as floor stand installation type; SHD-400 and models above should adopt
floor stand installation type.
When using the method to mount the dryer, the equipped standard base must
according to material inlet diameter of the molding machine mounting drill holes.
Then use the screw to fasten the base and the molding machine inlet.
17(28)
3.2 Floor Stand Installation

Floor stand installation type is to mount dryer on a floor stand, then via a
photo-sensor hopper receiver to convey the material to the feed port of a molding
machine. SHD-400 and above models should adopt floor stand installation type.
Machine should be placed on water-level floor to keep balance. If it is to be
mounted on a high surface(e.g. on a scaffold or a interlayer), should ensure its
structure and sizes can bear the weight and size of the machine.
3.3 Connecting the Power Source
According to circuit diagram of each machine to connect the power source. Notice
should be taken concerning if the power voltage is in compliance with the required
specifications, also if the switch and load are proper and safe.
Notes: Before connecting, the main switch should be off.
3.4 The Hopper Dryer Test
After ensuring all the circuits have been connected firmly, turn on the main switch
to"ON" status and pressing the "RUN/STOP" button on control panel. Then blower
runs, observe whether the rotating derection of the blower is same as the arrow
indicated direction. If it is not, randomly exchange two of the three power firing
lines and connect them firmly.

off time), OFF4(Thur. off time), OFF 5(Fri. off time), OFF6(Sat. off time),
OFF7(Sun.off time).
2) Hold “Menu” for about 7S, press “Up” or “Down” key to set ON1(Mon. start
time), ON2(Tues. start time), ON3(Wed. start time), NO4(Thur. start time),
ON5(Fri. start time), ON6(Sat. start time), ON7(Sun. start time).
4.1.7 Communication Setting (optional functions)
1) Press both “Menu” and “Up” for 3 seconds, it displays “PRO”
(communication protocol) setting.
Notes: communication protocol is fixed to Modbus RTU
protocol—“RTU”.
2) Press “Up” key to enter “ID” (communication address) setting;
Notes: The communication address of every controller in the
same system must be the only one, no repeat use. In principle:
communication address of hopper 1 is 1, communication
address of hopper 1 is 2, and so on.
3) Press “Setup” key, the set value flickers, then press “Up”or “Down” key to
add or decrease the value.
4) Press “Setup”key to confirm the input value;
5) Press “Up” key again and again, it displays “Baud” and “PAR” settings, (as
below )
6) Repeat step 3 and step 4, then confirm the related input parameters.
7) Press “Menu” key to return operation menu.

5. Maintenance and Repair
5.1 Blower
1) Clean the blower regularly (especially the air inlet path).
2) Eliminate the fan's dirt regularly to avoid the damage to the blower.
Note: No need for regular inspection because all the electrical
parts in the control unit are fixed tightly!
6. Troubleshooting
Fault Possible Reasons Solution
Blower rotating on the
contrary with arrow
Blower not turning
Blower not rotating
and not heating
No temperature for
blower runs while
The blower can run but
temperature is too low
Blower circuit connection reverse
phase.
1. Motor fault.
2. Failures of solenoid switch.
1. Overload jumped.
2. Transformer fault.
3. Fuse melted.
4. Power supply fault.
1. Lead sheet of heater pipe melted.
2. Magnetic switch fault.
3. Heater fault.
4. Controller fault.
5. Thermocouple fault.
1. Lead sheet of heater pipe fault.
2. EGO breaked.
3. Magnetic switch is lack of phase.
4. Controller is damaged .
Exchange two of theel ectrical wires.
1. Check and change.
2. Change or repair.
1. Check and change.
2. Check and change.
3. Check and change.
4. Check if lack of phase.
1. Check and change.
2. Check and change.
3. Check and change.
4. Check and change.
5. Change.
1. Check and change.
2. Check or re-set.
3. Check and change.
4. Change the temperature controller.
The blower can run but
1. Hot-air pipe is jam.
2. Controller is fault.
temperature is too high
3. Magnetic switch contacts stuck up.
Notes: Before inspecting or changing spare parts, ensure the main switch should be off.
1. Cleaning.
2. Change the controller or adjust PID.
3. Change.
