Some processes require a ramp with a gradual increase in power to
reach a new setpoint value. In addition, this ramp may require a
different gradient in order to switch from one setpoint to another. This
second value may be higher or lower than the original.
For example, a process may require a rapid heating period and a slow
cooling period.
It is for this reason that the MIC offers these two options. Two ramps
can be programmed independently - one to rise from «SP A» to a
higher setpoint value «SP B» and the second to reduce to a lower
setpoint «SP C».
Note:
This function can also be applied to switching from SP to SP2.
SP : Normal operating temperature of the process
SP2 : Temperature when idle.
Communication via the RS 485 serial link
compatible with C.BUS, MODBUS and
J.BUS protocol

This function continuously monitors current at the load.
It informs the user immediately of a break in the heating element.
MIC 48: Loads up to 100 A can be checked using an external current
transformer.
In addition, the load current can be monitored during the process.
Its value in amps can be read directly by pressing the
CTD 24: The software integrates this function without a sensor.
Two independent ramps for switching from one setpoint to another.
