TX20000U-KLC
Flux Indicates if there is a corrected flow of the coolant
H2o Pressure Indicates if the pressure of the coolant in the circuit is in the ran-
ge of admitted values. Alr means that the pressure is excessive
Blower-1 It indicates the state of the fan of the external unit
Blower-2 It indicates the state of the 2° fan of the external unit (only in the
transmitter TX15000U-KLC or higher)
Blower R It indicates the state of the fan of aspiration positioned on the top
of the machine
Pump-1 Indicates the state of the N°1 pump
Pump-2 Indicates the state of the N°2 pump
Change Pump <Ok>: pressing key OK it is possible manually switch the pump in function at
the moment. The minimal time between an exchange and an other is of 120 sec.
The pump is exchanged automatically every time you switch off and subsequently re-switch
the CCU. In case you never switch off the CCU, the pump is exchanged automatically every
10 days of normal operation.
The operation of pumps exchange is necessary for the regular functioning of the same.
In case of a fault on pump pressure, and then an interruption of the cooling flow, after 10 se -
conds is recorded by the machine which starts the operations of exchange pumps.
Note: the delay of 10 seconds is necessary to prevent the record of false positives
as a momentary pressure drop due to air bubbles in the cooling system.
The machine will continue to exchange the pumps every two minutes, until the situation that
caused the alarm is resolved.
After six minutes the equipment goes in a WAIT condition, and will be reported through the
yellow LED on the front, in the meanwhile the machine will continue to exchange pumps every
2 minutes in order to resolve the alarm condition.
If the alarm PRESS intervene, the transmitter should be in conditions of FAULT (transmitter
will not transmit more power) and this will be reported through the red LED on the front of the
machine. Only the intervention of an operator or a reset by telemetry, can unlock the transmit-
ter. If the problem remains, after 60 sec. return to FAULT.
Note: Please resolve as soon as possible the condition that brought the equipment
to the alarm, this to restore the correct operation.
Note: Please resolve as soon as possible replacing the faulty pump.
* The threephase control and the relative fuses are found near the input terminals on the top
of the machine.
