9.2.2

Heater Break alarm HB (only with the HB option)

This alarm is active when the load current decrease under the threshold set on the parameter P126H

(see par. 13).

The Heater Break alarm could be active also if there are a wrong wiring of the load.

When the problem is solved is necessary use the digital input: “Reset”

(Terminals 3-4).

The Heater Break circuit to work properly must have at least an input of 25% of the nominal current.

H.B. circuit read load current via a current transformer 25-50/0.05 or 100/0.05 depending on thyristor

size.

Minimum current is 30% of the current transformer size’s. If load current is below this value make two

turns or more around current transformer. H.B. circuit also diagnoses fuse failure.

Caution:

In the first start, and each time that the load is replaced, it’s necessary make the

Calibration procedure.

9.3

Calibration Procedure

The Calibration procedure is an automatic procedure that save in memory the value of load current.

To make the Calibration procedure follow these steps:

•

Turned completely in counter-clockwise sense the trimmer R13 (see par 10.3 )

•

Give the power supply

•

Press the “CAL” button on front unit, or use the configurable digital input (see par. 11.4).

•

All LEDS are on, this means that calibration procedure is active.

•

Turn the trimmer R13 in clockwise sense and set the wished current limit.

•

After a minute the values of voltage and current are stored in memory.

•

the CD3200 comes back to the initial situation.

The Calibration procedure is done.

Firing type

Choose an correct firing type allows to optimize the thyristor unit for the installed load.

The firing type has already configured in line with customer requirements that are defined in the Order

Code. The Order Code is written on the identification label.

However, if you wish to change the firing type you can use the software configurator or the parameter

on serial link (see par. 13).

Caution:

this procedure must be performed only by qualified persons.
