Problem:

Error message: Setup data corrupt / User data corrupt

 

Resolution:

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

Possible cause:

Diodes between IGBT’s are damaged

Measure /  exchange diodes:

Scroll down in the display menu until you reach the temperature display. Observe, if after crossing the switching threshold, the temperature doesn’t change, that the solenoid valve is blocked (when the 2nd thresholds are reached the message “over- or undertemperature” will be displayed).

NOTE: The error message “Ths too low (Ths = Temperature Heatsink)” might be an indication for a contaminated valve.

An overvoltage suppressor (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge suppressor attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold.

These surge suppressors are built in to the latest Pacemaker models and machine controls (from 2009).

Check, if one or more modules of the surge suppressors are red/defect. Replace the red modules.

Attention!!!

Do not bridge the signalling contacts and run the machine with defective red modules because they no longer protect the system from voltage peaks!!!
If the modules are defective, check the main supply. Measure and check all voltages between the phases and all phases to earth before exchange the modules and restart the machine.

Check

– Check the cooling-water-inlet.
– Check the “Ths” and “Tamb” on the display.
– Check the small fans of the Pacemaker

 

NOTE:
The error “Ths too low” means temperature heat sink (copperplate) too low. If the copper plate is too cold. It can damage the unit, if some condensation water flows to the electronic power parts.

 

Check if the valve closes correctly and clean the valve.

NOTE:
If you reassemble the valve, make sure you do it the right way (see picture)

 

Check the correct water flow direction.

NOTE: The pictures showing a regular Pacemaker and not a Pacemaker HF as used in the PowerCure, but the issue is the same!

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

When you start up your PowerCure equipment, the software version (here called generator data) will be displayed during the boot process.

Alternatively the information will we displayed, when press “MENU” and then press the key “down” several times until you get to “Preheater Info”:

There are two Software versions displayed:
e.g. – S/V 2.65 and EPLD V63

 

Possible cause:
Sparking on the induction coil

  • Make sure that there is a clearance of 3–5 mm between the coil and the canbody!
  • Make sure that the cooling water temperatur setting is correct (> 25°C) and you have no condensation at the coil. Condensation could cause a short circuit!

HF filter not set correctly (to high)

  • Check setting of PLL stfreq and HF filter. HF filter must be set 10KHz higher than the PLL stfreq. Go to the “system setup” to check.
    Note: The setting is password protected. If adjustment is needed, please contact Can Man.

Check all insulations of the coil and C-bar.

  • Download PDF here for more details!

Cause:

The water flow of the coil is too low!

NOTE:
The standard setting for this error is 3l/min (can be found in the basic setup “rotary minflow”).

 

The actual water flow is shown in the display. Press down from the main menu on the display until you find the flow coil.

NOTE:
You have to switch “ON” the curing to open the water valve!

Check for possible causes:

  1. Check correct connection of inlet and outlet!
  2. Clean inlet water filter.
  3. Check your input pressure, you shouldhave about 5 bar.
  4. Check if a water tube is bended ordamaged.

 

Clean the water valves:

Therefore disconnect the water inlet to the Pacemaker HF and blow out the water. Take off the coil and open the valve with a torx screwdriver. Blow out the valve and clean the rubber.

 

Reassemble the valve properly (insert the closing block with the spring on top, so the rubber is closing the outlet hole.

 

Clean the rotary flow unit. Follow the instructions below.

 

  1. Disassemble device by grabbing lens center hex with 7/16″ socket and turning 45° counter-clockwise. Pull on lens to unseat. Dismantle internal components.
  2. Clean body interior (rotor cavity and o-ring gland).
  3. Lube o-ring.
  4. Install o-ring to body o-ring gland.
  5. Install shaft to body.
  6. Install rotor to body on shaft (on top of washer).
  7. Install lens to body.
  8. Turn lens 45° clockwise to lock it.
  9. Pressure test to 50 psi to proof o-ring integrity.

If were not successful, replace the rotary flow meter => CM article No 007906

 

The reset LED flashes and a warning is shown!

If the reset LED flashes, then the system works in a critical state. The unit is still entirely functional, but it should be a hint for the operator to do something against the warning.

Contact Can Man for advice!

Possible cause:

  1. Check the water flow. Is the water flow reduced compared to before!
  2. Clean the external filter.
  3. Do you have a drop of pressure compared to before?
  4. Check the water quality.
  5. If you have increased the power, it could be, that the water temperature at the C-bank is higher than before.
    • you might increase the flow – contact Can Man for advice
      (only for CM technician turn the restrictor / valve by an eighth of a turn).

Please check on the white transformer all connections.

 

ATTENTION:
Switch OFF the main supply first!

 

Nuts must be firmly tightened, but do not overtight! Bolts must well fixed in the casting compound.

 

NOTE:
A loose connection creates an overheating and destroys the transformer and cables!

The IC, which control the analog output, must be replaced. Please request support from Can Man!

Possible cause:

  • Battery voltage low = DC voltage across the chopper too low
  • Supply voltage mains (all three phases) 400V
  • Check main contactor K1 all connections tighten
    If you doubt the functioning of the contactor , replace it with the same type.
  • After loading and switching on the MS signal (K11 in the control), the main contactor (K1) should switch on and there should be 400V at the out put of the contactor.
  • The triggering of F1 is not shown on the display, respectively the error is reported as “battery low voltage”. Reset the F1, when the error occurs again, increase the ampere value to 32 A.
  • Measure the voltage over the battery / capacitors in the standby condition. (min. 400 VDC)
  • Check the fuse at the 24V power supply (F1..F5)
  • Check if the relay K3 and K4 connections and plugged properly
  • If the message arises sporadically after a certain time, the receiver on the HF controller is probably defective. => Contact Can Man

CAUTION – HIGH VOLTAGE:
You are now in the immediate vicinity of parts that produce high electric voltage! There is a danger of an electric shock.

Only performed by “certified electricians”

 

  • Measure the voltage on the clamp J5
  • =>if the power output is set to 50V it should have about 100mVDC. (Running with curing “ON”)

Measure the voltage on the main board clamp 57=”+” 58= “-“ => if the power output is set to 50V it should have about 100mV.

• Check if the Dc-Dc IC has a problem you can exchange it with an other one on the board
(which is unused in your configuration – remove the IC carefully, so the pins are not getting damaged!)

  • If the measurement is still lower than 100mV, you have to replace or repair the C-Bar. (Can Man No. : 019817)
  • There is a problem on the voltage divider on the C-Bar (R1..R12). One of the welding pointsπ or SMD resistors are bad or damaged.R=150 kOhm
    among end of R1 and J5X : 900 kOhm among end of R7 and J4X : 900 kOhm
