3. Overview

This compact and light weight single-phase power controller is designed for high density panel installation, and can beapplied to a wide range of heating control applications with its various functions including phase-angle firing
system/zero-cross firing system selection, soft start time setting and lower limit setting.

Warnings / Cautions(1) Mounting direction

Mount your unit vertically with its main circuit terminals (U1, U2) placed downward to ensure air-cooling effects are
ventilated through the air duct structure.
(2) Do not use this unit on any desk.
Make sure to mount this unit on a panel to prevent malfunction or injury through it falling down.
(3) Mounting environment
Do not operate this unit at a place where explosive, inflammable gas or other dangerous vapors exist.
(4) Only Shinko or qualified service personnel may handle the inner assembly.
To prevent an electrical shock, accident, fire or other problems, repair, modification or disassembly of the unit may only beundertaken by Shinko or qualified service personnel.
(5) Turn the power supply OFF in case of any abnormal events.
If there are abnormal odors, heat, or other abnormal events, turn the power supply OFF, and inform the nearest agent of
Shinko Technos Co., Ltd.

For Safety and Security(1) Use your unit at lower than the rated current.
Confirm the rated current on the label attached on the upper side of the unit.
(2) Connect a load before turning the power supply on.
Never turn the power supply on without connecting a load in advance to prevent problems.
(3) Applicable load
A resistive load is applicable. An inductive load (transformer primary control, maximum magnetic flux density 1.25T) is
applicable only when the phase-angle firing system is selected.
(4) Mounting of a rapid fuse
Mount a rapid fuse (sold separately) for protecting thyristor elements.
(5) Countermeasures for digital units
Higher harmonic noises are generated when this unit is used with the phase-angle firing system. Use an insulationtransformer, separate your unit from a drive power line, or take other countermeasures.
(6) Do not use unused terminals.
Do not connect signals to any unused terminals to prevent problems.

Warning

Turn the power supply to the instrument OFF before installation.
Working on or touching the terminal with the power switched on may result in severe injury or death
due to electrical shock.
This instrument is a back panel type which is designed to be mounted inside a panel except foraccessories such as setting units.

2.1 Precautions for Installation) facing upward.

(2) Mount the unit in a clean and well-ventilated place free of
dust particles.
(3) Separate this unit from a high temperature generating unit orsimilar unit.
(4) Keep space for heat radiation (more than 200 mm) aboveand below this unit.
(5) Do not mount this unit in a place subject to vibrations andshocks.

Control System
Phase-angle Firing System
The system for controlling the output by changing the
conductive angle (ON timing) in the half cycle (180 )of the power supply. The control becomes continuous
as compared with the zero-cross firing system. This
control system is also used for transformer primarycontrol. However, since the output contains higher
harmonics, it may cause external noise.
Zero-cross firing system
The system for controlling the output by deciding
ON/OFF in every cycle of the power supply. Since thepower sypply is turned on from 0 V (zero cross point)
voltage, noise is recuded as compared with thephase-angle firing system. However, since themaximum current flows during each ON cycle it may
cause flickering.

Soft Start
This function is provided to increase the output
gradually up to the specified output when the power
supply is turned on or when the control input valuechanges abruptly. This function can prevent a surge
current from being generated due to an abrupt changeof the primary control output of transformer. You can set
the time (from 0% to 100% output) from about 1
second to 20 seconds.

The above figure shows the lower limit setting
when the gradient is set to 100%.

4.4 Soft Start Time Setting (SOFT)
The soft start time becomes approx. 1 second
when turning this trimmer fully counterclockwise,and becomes approx. 20 seconds when turning
this trimmer fully clockwise.

5. Wiring
Warning

Turn the power source OFF before wiring to prevent an electrical shock.
Wiring should be undertaken by the experienced person who has a good knowledge of wiring.

5.1 Wiring Precautions
For the main circuit wiring, use a cable which has a sufficient allowance for load current.
For wiring of the other terminals, twist 0.3 to 0.75 mm2 cables.

5.2 Main Circuit Terminals / Power Terminals (U1, U2 / 8, 9, 10)
Make sure that the phase of the main circuit (U1, U2) is the same as the phase of the power supply (8, 9, 10).
(U1 and 8, U2 and 9 or 10). If the phases do not match, normal output cannot be obtained.

6.1 Checking before Operation

Warning

Turn the power supply to the instrument OFF before checking. Working on or touching the terminal withthe power switched on may result in severe injury or death due to electrical shock.
(1) Check the connections again.
(2) Check the power voltage and the load capacity again.
(3) Measure the insulation resistance with a 500 V megger.
Short main circuit terminals U1 and U2 for the dielectric strength test.
(4) This unit becomes hot due to being a self-cooling type.
Make sure to mount the unit with the UP mark ( ) facing upward so as not to interrupt the heat radiation effect.
If the unit is mounted in a direction other than specified, the interior becomes hot and could cause malfunction orother problems.
(5) Check the control system selection again.

6.2 Operation

In the case of Auto running(1) Set the desired value (SV) on the indicating controller.
(2) If an Auto/Manual switch is connected, select it to “AUTO”.
(3) Set the gradient.
(4) Make sure that a stable control is performed.
If the control is unstable, change the parameters (PID constants in particular) on the indicating controller,
or adjust the gradient to an appropriate value.
In the case of Manual running(1) If an Auto/Manual switch is connected, select it to “MANUAL”.
(2) Set the desired output manually.
(3) Change the setting manually while monitoring the temperature.

7. MaintenanceWarning

Turn the power supply to the instrument OFF before checking, cleaning or maintenance work. Working on or
touching the terminal with the power switched on may result in severe injury or death due to electrical shock.

7.1 Daily Check and MaintenanceThe checking and inspection of the following points are required to keep this unit running under the best conditions at all times.
Items
Contents
Fastening of bolts and screws
If the bolts for the main circuit terminals (U1, U2), in which a large current flows, areon the terminal board
loose, they may become hot and cause wiring damage.
If the unit is mounted in a dusty place with conductive dust particles like iron
Cleaning
powder, dust particles attached to the unit, this may cause failure or problems due
to poor insulation. Remove dust particles attached using a cleaner.

7.2 Consumable Parts

Caution• To prevent an electrical shock or fire, only Shinko or qualified service personnel may handle the inner assembly.
• To prevent an electrical shock, fire or damage to the instrument, parts replacement may only be undertaken
by Shinko or qualified service personnel.
• For replacing consumable parts or other parts, please contact the nearest sales agent of Shinko Technos Co., Ltd.

Exchange Intervals
5 to 8 years

Working Conditions
The higher the ambient temperature the shorter the life span. In addition, life span
depends largely upon atmospheric conditions (kinds of gases, kinds and degree of
dust particles, etc.)
