7.1 Parameters for condensers coupled with inverter
compressors (CR011RA and CR021RA)
When HCR condenser will be connected to a CR011RA or
CR021RA (unit with Inverter Compressor) will be necessary
proceed as following:
1. Digital Filter OFF – DSw>8=OFF (see pag.7)
2. Select Bench Parameters (BK2)
3. Modify below parameter values:
Default parameter edit procedure
Proceed as follows to edit one or more parameters:
1.
Simultaneously press the ENT and ESC keys located under
the display;
2.
Using the or keys, scroll available parameters until the required
one is found;
3.
When the parameter is found, press ENT. "Program" will
switch to "Modify";
4.
Press to increase or to decrease the selected parameter value
(hold down to change faster);
5.
Press ENT to confirm changes;
6.
To edit another parameter, restart from point 2 or
simultaneously press the ENT and ESC keys to save changes
("Update" appears), or press ESC to cancel the operation and
return to the main screen.
N.B.:
If, due to incorrect parameter settings, the regulator has regulation
problems, we recommend you restore default parameters

Signals
Circuit breaker and short circuit protection
A series of fuses (Protistor fuses) are installed on the ESD regulator
to protect the power module.
A circuit breaker (max 20A) with AC trigger curve installed upstream
from the regulator is recommended.
SURGE ARRESTER :
Electrical protection inserted between the regulator power supply
and grounding, that protects the device from transitory power
surges.
WARNING:
Disconnect the faston contact from the PE ground
reference, in the electrical rigidity test.
WARNING:
For
DIFFERENTIAL
components with grounded current dispersion ≥ 60 mA.
ESD has a grounded current dispersion of about 1 mA.
