Ensure that all recommendations for compliance to mounting, electrical safety, EMC and UL regulations have
been adhered to.
1.1 Pressure transmitters
Warning: Only use approved pressure transmitters!
This refrigeration application is preset for use with the following Huba Control pressure transducers:
1. Basic information on rst set-up
Low Pressure pe: -0.5 … 7.0 bar
A REFR-P-TRANSD-LP7N+PL
High Pressure pc: 0 … 30 bar
A REFR-P-TRANSD-HP30N+PL
For alternative pressure transmitters and pressure ranges refer to Parameter SP0, p. 6 of Planning Guide.
1.2 Recommendations
•It is important to ensure that an interlocked contactor is fitted between the Refrigeration Inverter and the
compressor if a parallel bypass connection is used.
•In particular ensure that two isolated contacts of a relay are connected to the Safe-Torque-Off inputs of
FrigoPack®FU+ Refrigeration Inverter: STO-A (Terminal X10:1) / STO-B (Terminal X10.3).
• Remove start command (cable to terminal X13:2)
• Connect main power supply
• Verify that the blue LED for suction pressure lights on module BM-1. If not, then check if the wiring of the
pressure transmitter is correct.
• If a discharge pressure transmitter is used, then verify that the red LED lights on module BM-1. If not, then
check if the wiring of the pressure transmitter is correct.
• Measure the pressures with a refrigeration pressure gauge. Verify that the pressures indicated in menu
OPERATION at parameter 03: pe_RACK_pc agree with these external measurements.
