Thermomagnetic Circuit Breaker Q2; Replacing The Electronics Block - Ingecon Sun 250 M220 Indoor Installation Manual

Installation manual
To verify that the emergency stop button works properly, check for continuity between
terminals X7n.2 and u1n.x3.9, and u1n.x3.9 and J19.8.
See illustrations on pages 81 and 85.

9.4.8. Thermomagnetic circuit breaker Q2

The Q2 thermomagnetic circuit breaker belongs to the
switching filter. The way to determine the reason for
shutdown of the Q2 thermomagnetic circuit breaker
will be by performing the following procedure:
1. check that the protection in question is
turned to maximum. If not the case, calibrate it to
the maximum and check operation.
2. If the problem persists, check that the capac-
itance of the switching harmonics filter in each of
the three phases is adequate. use a multimeter
to measure the capacitance between phases and
check that all have the same value. If not the case,
proceed to replace the filter.
3. If after taking the 3 steps above the problem
persists, take note of the unit's serial number and
look at what version of firmware it has. If you do
not know what version of firmware the equipment
has, it will be enough to power the unit with Dc
and check it through display by: OK
Status. The status will show digit coding of the
form _Letter, whereby the letter indicates the unit's firmware version. ensure that the firmware version is letter
n or later. With all this information, call customer Service on the number on the cable protectors on the base of
the unit's door.

9.5. Replacing the electronics block

The unit's main electronic boards (control board, power board, IgBTs, etc.) are its core element, and they are grouped
in a stainless steel cabinet known as the "electronics block".
In case of equipment damage requiring the replacement of this "electronics block", proceed as follows:
The electronics block is a heavy element. We suggest that it be carried by two people or with mechan-
ical assistance.
When handling the block, personal protective equipment (PPe) must be worn: helmet, glasses and
safety footwear.
The tools needed to replace the electronics block are:
• Flat screwdriver for terminal connections.
