Emergency System - Rivacold P Mode D'emploi Et D'entretien

6.1.2 Verification of Material Availability
With an advance of at least 60 days from the fixed date for maintenance interventions, conduct a detailed examination of the
necessary material:
1. check the material is in the warehouse,
2. if necessary, ask the manufacturer's Technical Office for the missing pieces, at least 30 days in advance.

6.2 Emergency system

DANGER::
DANGER:
.
If a functioning fault or anomaly occurs on the electronic central unit and immediate replacement is not possible, the
EMERGENCY SYSTEM can be used to maintain the unit operational until the central unit is replaced. To use this system, having
sectioned the machine, proceed as follows:
1. Remove all bridges on the L terminals and the common ones on the board relays (terminals 25-28- 33-36-38);
2. As reported in the diagram in Figure 7, connect a thermostat between terminal L, the NO terminals (terminals 32,37) and
the NC terminal (terminal 34) of the relays on the compressor, defrosting and fans (COMP, DEF and FAN).
3. Then make a bridge between the L terminals and the NO terminal of the ON/OFF relay (terminal 26 for power supply of the
tolerance on the carter, door and drainage where present).
4. Connect the Blocksystem SF or P or SV again to the power line and set the thermostat to the desired temperature.

When installing the new central unit, restore all the connections described in points 2, 3, 4 and 5.

Legend:
T = Thermostat
for the machine, only operators correctly trained and informed on the risks present can intervene on
the machine and only having fully read this use and maintenance handbook. The manufacturer
declines all responsibility for any damage to property and/or persons deriving from improper
interventions conducted by unqualified, untrained or unauthorised staff.
before conducting any planned cleaning interventions, ensure the machine is sectioned from the
power supply, and any hot surfaces have cooled.
what we've described is a temporary connection! As soon as possible contact the vendor or directly
contact the manufacturer to replace the non-operating board.
during the entire emergency phase, defrosting is excluded, therefore we recommend you reduce
opening the coldroom to a minimum.
