1.1 Profile
The THYRITOP 500 series of microprocessor advanced solid
state power units controls, in compact and optimized size, high
electric powers with different types of heating elements, single-
phase, biphase or triphase. Current levels range from 40A
to 250A, nominal voltage from 480 VAC to 600VAC.
The command input is congurable and accepts 0-10V, 0/4-20mA
signals, potentiometer, logic signals, including with PWM modes
for cost effective solutions.
The device can also be operated via Modbus RTU serial
communication, with IN/OUT chain connections facilitated
by plug-in RJ10 (telephone) connectors.
The several trigger modes are software congurable and provide:
- ZC : Zero Crossing constant cycle time (settable in range
1-200sec), for conventional loads.
- BF : Burst-Firing, Zero crossing with optimized minimum cycle
time, for systems with low thermal inertia, medium-wave IR lamps.
- HSC : Half Single Cycle Zero Crossing corresponds to Burst
Firing that manages single semi-cycles of conduction or stop
cycles, useful for short-wave IR lamps, reduces ickering and
limits generation of EMC noise on the power line (applied only
to single-phase load or open delta).
- PA: Phase angle control, useful for short-wave IR lamps,
transformer primaries. Completely eliminates ickering of load
laments, but generates EMC noise on power line (harmonics).
Soft Start and soft stop ramp functions can be assigned to these
controls with limitation of current peaks and/or maximum RMS
current level.
Thanks to sophisticated Hardware and Software solutions,
you can precisely control different types of loads.
Phase angle control (the only control method that completely
eliminates IR lamp ickering), matched with current, voltage,
or load power feedback functions, allows the easy use of “critical”
applications such as (for example), special resistors such
as special Super Khantal™ heating elements, Silicon Carbide
resistors, or transformer primaries either single-phase or triphase.
THYRITOP 500 runs complete diagnostics of current, voltage,
power, and temperature levels:
Current Diagnostics:
- Total and partial load interrupt alarm
- Self-learn function of alarm limit for interrupted load
- Alarm for SCR in short circuit
- Alarm for load in short circuit or overcurrent
Voltage Diagnostics:
- Alarm for absence of phase
Temperature Diagnostics:
- Alarm for over temperature of power module
1 • PRELIMINARY INSTUCTIONS
Power control with Soft start ramp limits load, optimizes
the consumptions and increases the load operating duration.
Device parameters can be congured from PC, by means of
a simple conguration SW which lets you save all parameters
in a conguration le that is easy to manage and to copy to other
devices.
Moreover, an RS485 serial connection of THYRITOP 500 is
offered with Modbus RTU protocol to control currents, voltages,
powers, load status, and device status from the supervisor terminal
(HMI) or PLC.
The section contains general information and
warnings to be read before installing, conguring
and using the controller.
1.2 General DescriPtion
THYRITOP 500 is single-zone advanced solid state power unit,
extremely compact, equipped with different optional functions;
it offers an exclusive combination of performance, reliability,
and exibility.
In particular, this new line of CA PYROCONTROLE controllers
is the ideal solution for sectors demanding high performance
and continuity of service, such as :
• Thermoforming
• Blowing
• Hot runners for injection presses
• Texturizing of bers
• Heat treatment furnaces
• Woodworking machines
• Glass tempering furnaces
The modules series THYRITOP 500 controllers are based
on an extremely versatile hardware and software platform,
with options to select the best I/O conguration for your system.
THYRITOP 500 is used for the power control of single-phase
and 2-phase loads, including resistive loads with high and low
temperature coefficient, short wave IR lamps, or transformer
primaries.
