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

• Check first whether the conveyor / elevator unit is blocked somewhere!
• Check the 24 VDC fuse according electrical diagram. Make sure that the correct size will be used!
• Check the setting of the respective sensor (according electrical diagram), which allows the conveyor to move if the sensor is active / free!
• Take the 24 VDC motor out, and check whether the motor is defective or not! Make sure that the conveyor is not moving downwards as soon as the mechanical connection between motor and elevator unit has been released!
