Description Multifunction programmer/ step controller size
72x72mm. ATR620 has been specifically
developped as control system for glass,
ceramics and heat treatments kilns and
furnaces.
Double display enables visualization of setpoint
and process value, selected cycle, temperature
at step end, output percentage, time elapsed
from start, step in progress, power
consumption/KWh. Fast advancement on cycle
and manual control of output percentage to
assure precise monitoring of the plant.
If it is necessary to monitor two zones
(example: kilns with extended chamber), the
?double loop? function is very useful to
compare the reading of two sensors and keep
uniform temperature inside the chamber.
For each of the 15 programmable cycles, it is
possible to program 20 steps/segments.
Special software functions provide high
accuracy of firing profile for sensitive
materials:
-Waiting function (useful when the plan cannot
reach setpoint within the programmed time)
-Recovery function (with automatic or
selectable gradient) in case of power failure.
Additional features include: 2 programmable
digital inputs for Start/Stop/Alarm; operating
as simple controller with programmable
setpoint; starting setpoint; relay/SSR outputs
for the management of heating groups,
burners or auxiliary alarms; delaied start;
Master/Slave mode for serial line
(RS485+MODBUS-RTU protocol, up to 32
control loops). |
