Be especially careful to read and follow all cautions that apply to your application. A “WARNING” safety alert appears with information that is important for protecting you, others and equipment from damage. Pay very close attention to all warnings that apply to your application.
1.1. Safety notes
WARNING! To avoid damage to property and equipment, injury and loss of life, adhere to applicable electrical codes and standard wiring practices when installing and operating this product. Failure to do so could result in damage, injury and death.
WARNING! All service including inspection, installation, wiring, maintenance, troubleshooting, fuse or other user
serviceable component replacement must be performed only by properly qualied personnel. Service personnel must read this manual before proceeding with work. While service is being performed unqualied personnel
should not work on the unit or be allowed in the immediate vicinity.
WARNING! When in use the power controller is connected to dangerous voltages. Do not remove the protective
covers without rst disconnecting and preventing power from being restored while servicing the unit.
WARNING! Do not use in aerospace or nuclear applications.
WARNING! The power controller’s protection rating is IP20 with all covers installed and closed. It must be
installed in an enclosure that provides all the necessary additional protections appropriate for the environment and application.
WARNING! Ground the power controller via the provided protective earth grounding terminal. Verify ground is
within impedance specications. This should be veried periodically.
WARNING! Electric Shock Hazard: when the power controller has been energized, after shutting o󰀨 the power, wait at least one minute for internal capacitors to discharge before commencing work that brings you in to contact with power connections or internal components.
WARNING! The installation must be protected by electromagnetic circuit breakers or by fuses. The semiconductor fuses located inside the power controller are classied for UL as supplementary protection for semiconductor devices. They are not approved for branch circuit protection.
WARNING! When making live voltage or current measurements, use proper personal protective equipment for
the voltages and arc-ash potentials involved.
WARNING! Verify the voltage and current ratings of the power controller are correct for the application.
www.west-cs.co.uk 6
CAUTION: To avoid compromising the insulation, do not bend wire or other components beyond their bend
radius specications.
CAUTION: Protect the power controller from high temperature, humidity and vibrations.
CAUTION: The power controller warranty is void if the tested and approved fuses are not used.
CAUTION: Only trained and authorized personnel should access and handle the internal electronics and they
must follow proper electro-static prevention procedures.
CAUTION: Install an appropriately sized RC lter across contactor coils, relays and other inductive loads.
NOTE! Provide a local disconnect to isolate the power controller for servicing.
NOTE! The nominal current is specied for ambient temperatures at or below 40° C. Ensure the application
design allows for adequate cooling of each power controller. The power controller must be mounted vertically. The cooling design must prevent air heated by one power controller from causing power controllers mounted above to exceed the ambient operating temperature limit. When power controllers are mounted side by side allow a minimum spacing of 15mm between them.
NOTE! Use only copper cables and wires rated for use at 90°C or greater.

3. Introduction

A thyristor unit is semiconductor device which acts as a switch formed by two thyristors in ant parallel.

To switch on the alternating current the input signal will be on and the thyristor will switch o󰀨 at rst Zero Crossing
voltage with no input signal.
The benets of thyristor units compared with electromechanical contactors are numerous: no moving parts, no
maintenance and capacity to switch very fast. Thyristors are the only solution to control transformers and special loads that change resistance with temperature and with age.

3.1. Advantages compared with analog thyristor unit

Communication RS485 is a standard feature of Relay C. this allows the use of many information like: current, power,
load state and all the parameters for diagnostic and conguration. Ulterior advantages of the digital system vs the analogical is the exibility and the possibility of implement special characteristics without change the hardware. Several strategies can be implemented and selected through the conguration parameters. With the software Thyristor Congurator, you can have access to the conguration parameters.
To connect the Thyristor unit to the computer use a micro USB cable.

5. Quick Start

Attention: this procedure must be carried out by skilled people only.
If your Relay C code is in line with what you really need, then the main conguration is already done by Producer and
you just need to do the following steps:
1. Verify Relay C current sizing. Be sure that:
the load current is equal or less than the nominal one of Relay C
the main voltage is equal or less than the nominal voltage of Relay C
2. Verify the Installation
3. Verify the Wiring:
all auxiliary connections must be done in line with wirings on this manual
verify that there isn’t a short circuit on the load
4. Supply the auxiliary voltage of the unit in the Set menu
Set the parameters Operative Load Voltage and Nominal Current of the load using the frontal keypad or Thyristor con-
gurator software.
The auxiliary voltage supply of the Relay C unit must be synchronized with load voltage power supply.
If the Auxiliary Voltage (written on the identication label) is di󰀨erent from Supply Voltage (to the load), use an
external transformer.
If your Relay C code is NOT in line with what you really need, use the congurator software tool to set-up the
unit. Install the software on your PC, select Relay C and click on test unit changing what you need.

9.7. Calculating ow capacity of the fan
All the thyristor units when are in conduction produces power loss that is dissipated inside cubicle in terms of heating. Due to this fact the internal temperature of cubicle is higher than ambient temperature. To be cooled the thyristor need of fresh air cooling and to do it is normally used a fan mounted on the front door or on the roof of the cabinet. Procedure to size Fan air mass ow (V): see power loss for each thyristor and fuse mounted indicated in the manual related to the current (Output feature and Internal fuse Chapter).
V = f *
The formulas used are for information only and is not a substitute for a proper thermal rating
done by a qualied person.
Qv
tc-ta
Qv = total power losses (w) (thyristor + fuse power loss)
ta = ambient temperature (°C)
tc = cabinet temperature (°C)
V = fan air mass ow (m³/h)
f = altitude coe󰀩cient (see
table on right)
Altitude
0:100 meters f = 3.1 m³K/Wh 100:250 meters f = 3.2 m³K/Wh 250:500 meters f = 3.3 m³K/Wh 500:750 meters f = 3.4 m³K/Wh

10. Installation

Before to install, make sure that the Thyristor unit have not damages. If the product has a fault, please contact the dealer from which you purchased the product. Verify that the product is the same thing as ordered.
The Thyristor unit must be always mounted in vertical position to im­prove air cooling on heat-sink. Maintain the minimum distances (*)
in vertical and in Horizontal as represented, this area must be free from obstacle (wire, copper bar, plastic channel).
When more unit has mounted inside the cabinet maintain the air cir-
culation like represented in gure without obstacle for the air ow. Is
necessary to install a fan to have better air circulation as calculated previously.
The V Air ow must be equal or more than the value calculated. If the cabinet fan mounted by the customer have an air ow lower
than the correct value the warranty will decay.

11. Wiring instructions

The Thyristor unit could be susceptible to interferences lost by near equipments or by the power supply, for this reason in accord to the fundamental practices rules is opportune take some precautions:
The coil contactor, the relays and other inductive loads must be equipped with opportune RC lter.
Use shielded bipolar cables for all the input and output signals.
The signal cables must not be near and parallel to the power cables.
Local regulations regarding electrical installation should be rigidly observed.
Use 75°C copper (CU) conductor only, wire ranges (AWG), wire terminal type (ZMVV), terminal tightening

Choose a correct ring type allows to optimize the thyristor unit for the installed load. The ring type has already congured in line with customer requirements that are dened in the Order Code. The Order Code is written on the identication label. However, if you wish to change the ring type you can use the software congurator or the Control Panel.
Caution: this procedure must be performed only by qualied persons.

14.1 Zero Crossing

ZC ring mode is used with Logic
Output from temperature controllers and the Thyristor operates like a cont actor. The Cycle time is performed by
temperature controller. ZC minimizes
interferences because the Thyristor unit switches ON-OFF at zero voltage.

14.2 Single Cycle

Single Cycle it’s the faster zero crossing switching method in relationship of the power demand from a temperature regulator or from an external signal. With input signal at 25% the output is one cycle ON and three cycles OFF With input signal at 50% the output is one cycle ON and one cycle OFF With input signal at 75% the output is three cycles ON and one cycle OFF With input signal at 76% the output is the same of 75% but for each ON cycle the microprocessor divides 76/75, and when the sum of rests is
one, the unit does one more cycle ON. For this ring is necessary to have analog input.
The Single Cycle is used to control the loads with low inertia or for infrared lamps to short wave.

14.3 Burst Firing

The Burst Firing is similar to the Single Cycle, but consecutive cycles ON are selectable between 1 and 255, with input signal equal at 50%. When 1 is speci-
ed, the ring type is Single Cycle.
Burst Firing is a method zero crossing that it reduces the electromagnetic interferences because the thyristor switches at zero voltage crossing. The example show the Burst Firing with Burst cycles=4.

This is an additional function to the Burst Firing. The unit start in phase angle mode with a ramp starting from zero up to the full tension in the cycles number set in the parameter. When the ramp is over, the thyristor unit will stay in conduction at full voltage up to the end of cycles of
burst. The S+BF ring is used to control small
inductive loads to avoid inrush surge current and to reduce the electromagnetic interfer­ences.
The example show the ring with Burst
cycles =4 and start ramp half cycles=3.

14.5 Phase Angle

The Phase Angle ring allow the control of the power on the load, for this ring
the thyristor can be in conduction only for a part of the voltage cycle. This part of the voltage cycle is adjustable in function of the input signal from 0 at 100%.
The PA ring is normally used for control
the inductive loads, and is also possible control a primary of transformer coupled with the cold resistances like: Superkanthal, Molybdenum, Platinum, Tungsten or Quartz Lamp. The only disadvantage with phase angle is the possible generation of interferences that however can be reduced with opportune
lters.

14.6 Soft Start with Phase Angle

This is an additional function to the
Phase Angle. The ring angle of the
thyristor increase or decrease up to the
nal setpoint value.
The Soft start ramp is an important feature to reduce the inrush current with transformers during the during the cycle of magnetization or with cold resistance that are near to the short circuit when they are supplied. Setpoint Ramp Up / Setpoint Ramp Down.

The Delay Triggering ring is used
the control a primary of transformer coupled with the normal resistances on the secondary (N.B. don’t connect cold resistances on the secondary like: Superkanthal, Molybdenum, Platinum, Tungsten, Quartz Lamp). For an inductive load (ex transformer), switching the thyristors at zero crossing can generates transient over currents

that can blow the fuses, to avoid this problem you must use the Delay
Triggering. This ring delay the rst
half cycle of Burst for an angle from
0 to 100° relative to the zero. For understand the Delay Triggering ring, we have represented the waves generate by vectors that rotates in
counterclockwise:
over currents is reduced and the fuses don’t blow. The angle alpha is the delay to have i1=0 and this angle depends on the power factor.
The delay angle suggest for most applications is 80°.

15. Current Limit

The Current Limit is available on REVO CL with Phase Angle ring mode only. It control the ring angle of the thyristor to maintain the three RMS current under the set value. When the current exceeds this value, the voltage is decreased up to reach the current limit set
I load ≤ I limit set I load > I limit set

15.1 Current Limit SettingThe setting of the current limit value can be done in two ways: Digital or Analogic.

• Digital: Set the parameter from the hardware menu Set the current limit value by the parameter . from 0 to 100% of the Current. (Operator menu)
• Analogic: Set the parameter from the hardware menu The value of the Current Limit is setted with analog input 2 Terminals 11 (-) e 4 (+).
This analog input is 0 – 10V and input impedance 10Kohm. The settings functions by the analogic input 2 is called also External current limit prole because allows to change the prole of the Current Limit during the process.
Caution: this procedure must be performed only by qualied persons.

15.2 Current Limit tuning procedure

Give the power supply and set the current limit to zero:
- In analog mode, set the analog input 2 to zero
- In digital mode, set the parameter=0
Start the thyristor unit.
Set the primary input or the setpoint value at 100%
Increase the current limit
- In analog mode increase the value of the analog input
- In digital mode increase the parameter until to reach the desired value of rms current.
Stop the thyristor unit. The Current Limit Procedure is done.

16. Bakeout in function

16.1 What is heater bakeout?

If a MgO-insulated heater element shuts down for a long period of time (or sits in storage), it can absorb moisture. If full power is applied, excessive current can damage the heater or blow fuses. The heater bakeout feature soft starts the load to remove moisture from the heater and prevent blown heaters and fuses.

16.2 How does heater bakeout work?

During heater bakeout, the Power Unit slowly increases voltage to the heater while monitoring the output current:
• If the heater achieves full output before the bakeout time expires, then the heater is dry and can be put into service.
• If the output current reaches a user-specied trip point during the bakeout - as it would if arcing occurred in the heater - then the Power Unit shuts o󰀨 the output and activates an alarm.

17. Control Mode (feed-back)

The Control Mode (feed-back) type has already congured in line with customer requirements that are dened in the Order Code. The Order Code is written on the identication label. However, if you wish to change the Control Mode (feed-back) type you can use the software congurator or
the Control Panel.
Caution: this procedure must be performed only by qualied persons.
The Control Mode (feed-back) type is dened by the parameter Control Mode (feed-back) in setup menu. If the congurable digital input has set like feed-back Selection, it’s possible to change the select feed-back
with the Voltage feed-back (V) simply activating the input. It’s possible to have:
2
V
V2 = Square Voltage feed-back. The input signal is proportional to the output square voltage. This means that input signal becomes a power
demand. The power remains constant if the load impedance doesn’t change.
V
V = Voltage feed-back. The input signal is proportional to the output voltage. This means that input signal becomes a voltage demand.
This control mode compensates the voltage uctuation of the incoming line supply.
I
I = Current feed-back. The input signal is proportional to the current output. This means that input signal becomes a current demand.
This control mode maintain the current also if the load impedance changes.
VxI
P(VxI) = Power feed-back. The input signal is proportional to the power output. This means that input signal becomes a power demand.
The power remains constant also if voltage and load impedance change. This control mode is used with silicon carbide elements that change its resistive value with temperature and with age. In addition it compensates the
voltage uctuation of the incoming line supply.
2
I
I2 = Square Current feed-back. The input signal is proportional to the output square curren. This means that input signal becomes a power
demand. The power remains constant if the load impedance doesn’t change.
None = No feed-back Open Loop. The input is proportional to the ring angle (α).
EXT
External = External feed-back (0÷10V, 4÷20mA, 0÷20mA). The input signal is proportional to an external signal. This means that input signal becomes a demand to
maintain this signal always constant. This control mode is used for example with galvanic systems, where it’s necessary to control the current value through the electrodes.
