How To:

1. Switch off cooling unit.
2. Switch off main power. Wait 10 min until the capacitors inside PM HF are discharged before removing cover.
3. Before you remove any cable, take some picture and note how they are connected.
4. Disconnect the cables and water tubes on the c-bank.
5. Disconnect the Powercable and the water tubes on PM HF unit.
6. Disconnect the signal cable (Plug Sub D 25 Pin) and the panel cable (Plug Sub D 9 Pin).
7. Disconnect the two valve cables inside PM HF.
8. Remove the PM HF and replace with new or spare unit.
9. Reconnect all cables.
10. ATTENTION: Check the coil before connecting it!
    • Coil must be dry.
    • Insulation must be in good condition!
    • All connections inside could must be fixed well.
    • See also FAQ: Sparking on the induction coil! Error: “Output overcurrent”, “CH-driver fault” or “Frequency abnormal”
11. Double check all connection before switching on the main power.
12. Compare the settings/parameter and change it if necessary. For instructions which parameters has to set and how to do please contact Can Man
13. Re-start the PowerCURE™

Reason for error message:

• The Pacemaker™ HF has detected a missing phase.

Possible causes:

• Supply voltage mains (all three phases) 400V
• Check the small fuses on the bottom of Pacemaker HF
• Check complete wiring, Are all clamps tightened?
• Measuring voltage at the input terminals on the main board (see attached picture)
• IC “OC14” or phase measurement is defective. Replace the IC, Type HCPL3700

Potential remedy

• Check the „over voltage limit“ in the basic-setup.
  Password for overvoltage (max. 900V) = “MENU-DOWN-ENTER-UP-DOWN-UP”
• Check the “voltage limit” in the basic setup.
  Password for “voltage limit” (max. 565V) = “UP-DOWN-ENTER-UP-MENU-DOWN”
• Check the inputvoltage (400Vac).
• Is the wiring between C-bar (voltage measuring) and HF controller correct?
• Check the voltage signal over the C-bar. The voltage peaks should not be higher than the “over voltage limit”. To measure you need a scope meter and a differential probe or a scope with isolation to ground. See the pictures of tools, where to connect and how the signal looks if everything is fine.
• Check if the IC OC17 (Type 6N137) is faulty.
  
• Try to start the generator. If not successful, request support.

Possible reason choke coil defective

• Separate the choke coil from the original circuit and measure with an inductor → if the inductance is reduced a lot it mean is defective
• original value = 320 microHenry
