- Cooling unit does not work correctly. 

 

COOLING UNIT ENABLE TEST. 

Correct? 

‰

 

Control board (38), connector J20, terminals 2 - 4 = 0 Vac, contact closed, unit connected (27 

Vac, contact open, unit not connected) with Power Source powered (this signal is actually 
disabled by means of a jumper in the flow meter wiring). 

 
 YES 
 
 NO 

♦

 

Check the wiring between connector J20 control board (38) and flow meter (12). 

♦

 

Make sure there is a jumper in the wiring of the flow meter (12) that puts 
terminals 2 and 4 of the patch connector in contact on J20 of control board (38). 

♦

 

With Power Source off, temporarily disconnect J20 from control board (38), and 
make sure that when the Power Source is turned back on, on terminals 2 and 4 of 
J20 on control board (38) voltage = 27 Vac. If incorrect, replace control board 
(38). 

♦

 

Replace the control board (38). 

♦

 

Replace the control board (38). 
 

FLOW METER (12) TEST. 

Correct? 

‰

 

Control board (38), connector J20, terminals 3 - 4 = 0 Vac, contact closed, flow correct (27 

Vac, contact open, insufficient flow) with pump (13) running. 

 
 YES 
 
 NO 

♦

 

Check the wiring between connector J20 control board (38) and flow meter (12). 

♦

 

Make sure that the lines of the cooling circuit are not clogged. 

♦

 

Make sure that the hydraulic circuit is under pressure. If not, check the pump (13) 
and replace if defective (see test below). 

♦

 

Check the level of the cooling liquid in the tank (10). Top up the tank if below 
minimum level. 

♦

 

With Power Source off, temporarily disconnect J20 from control board (38), and 
power up the Power Source again to check, on terminals 3 and 4 of J20 on control 
board (38) voltage = 27 Vac. If incorrect, replace control board (38). 

♦

 

Make sure the flow meter(12) is functioning. If defective, replace. 

♦

 

Replace the control board (38). 

♦

 

Replace the control board (38). 
 

PUMP (13) TEST. 

Correct? 

‰

 

Terminal of the pump (13) = approximately 230 Vac, with Power Source powered. 
 
 YES 
 
 NO 

♦

 

Check the wiring between terminals J8-A and J8-B of pre-charge board (45), fuse 
in the rear panel of the Power Source, terminals of the pump (13) and fast-on 
patch terminals from the voltage change of the transformer (27).
