Safety information and protective measures 1.1
WARNING
WARNING
Risk of death, injury or material damage.
Strictly follow
- the product-specific safety information, the general safety
information in the document TD00-000.860.01... and the
safety information according to ARTD Part 2.
¹ Non-compliance can lead to death, injuries, or material
damage.
X-ray radiation!
When working on the system where radiation has to be
released, comply with all radiation protection directives and
the rules for radiation protection according to
ARTD-002.731.02.
¹ Non-compliance can lead to illnesses, irreversible
damage to body cells and to genetic make-up, severe
injuries, or death.
¹ Use available radiation protection devices.
¹ Wear radiation protection clothing (lead apron).
¹ Maintain the greatest possible distance from the radia-
tion source.
¹ Release radiation only if necessary.
¹ Set radiation activity as low as possible (low KV and
mAs values).

WARNING
POLYMOBIL Plus! (with X3 connected!)
To avoid electrical shock from components under voltage,
also be aware that:
The capacitor bank might still carry a charge. Do not attempt
to work on the system while this condition exists.
After switching off the system, approximately 450 VDC may
still be present in the system even after disconnecting the
line voltage plug. Within 10 minutes, this voltage will drop to
approximately 10 V.
¹ Inspect LEDs V40 and V41 on D927, which is dis-
charged with the bank.
¹ Measure the voltage between the chassis and the right
side of F5 (D927) --> X3 connected!
¹ Before beginning any service work, wait until the volt-
age drops to approx. 10V within approx. 10 minutes;
the LEDs V1 to V10 on D 971 are then off (each of them
represents the voltage in one condenser).
¹ If one or more fuses on the D 971 have responded, high
voltage may still be present at the affected capacitor
even after a prolonged period of time.
¹ If connector X3 or X9 on D 927 or D 952 are not inserted
or there is a defect in the circuit, the capacitor bank will
not discharge. This can cause life-threatening voltage
to be present in the system even after a prolonged
period of time.
¹ Refer to the POLYMOBIL III/ Plus “Replacement of
parts, SPR8-125.841.10... ".

WARNING
POLYMOBIL III! To avoid electrical shock from components
under voltage, also be aware that:
After the system is switched off, around 300 V direct voltage
are present in the control console for the main inverter.
¹ Before beginning any service work, wait until the volt-
age drops to approx. 12V within approx. 1.5 minutes;
the LED‘s V92 and V93 on D922 are then off. V92: - 330
V, V93: + 330 V, see (Fig.1/p.9).
• Connect the POLYMOBIL Plus / III only to a line voltage supply (receptacle) that com-
plies with the requirements of VDE 0107 or corresponds to the local national standards.
• In general, switch off the system and disconnect the power cable from the mains prior to
any service work.
• Remove or insert boards with the generator switched OFF only; observe ESD guide-

Error 4 Static short circuit of the main inverter
System status:
Standby
Explanation:
Action:
• Check the power supplies U1 / U2 and the connections to
the main inverter.
¹ Some other possible causes are: capacitor C1 or
D922 may be defective.
• Disconnect capacitor C1.
- Warning: Turn off the equipment. Wait 10 minutes for it
to discharge. Turn it back on.
- If the error disappears, then it might be the tube, C1, the
cables and/or the connections to the tube.
Error 6 - IH heating measured < IH of preheating 0
Error 6 IH heating measured < IH of preheating
System status:

Explanation:
Action:
• Compare IH and IHS in D916 to make sure they are not the
same.
• Check the frequency of the heating inverter in the D916
TP - FC1.
• Check the form of the resonance current at the TP-I D916
(use Service Program 9).
¹ Possible causes are a bad cable connection from
D916 to D1(X8) (high resistance) to the single tank, a
defective heating inverter on board D922, a defective
heating transformer (single tank), the filament in the
single tank is defective, the D916 and/or the D922 are
defective, or the tube is defective.

Error 11 - Voltage too high in the capacitor bank 0
Error 11 Voltage too high in the capacitor bank.
System status:
Standby
Explanation:
D916 (CPU) detects overvoltage (> 440 V) in the capacitor
bank. After the system is switched on, the capacitor bank voltage is about 440 V (VC). This voltage is reduced to 1% of its
former level and the reduced voltage can be measured on
board D916, TP VC.
Action:
• Check the VC test point of the D916 and check the voltage
directly in the capacitor bank VC (possible point: HVVC in
D922).
Error 12 - Noise in the static short circuit signal in the heating inverter 0
Error 12 Noise in the static short circuit signal in heating
System status:
Standby
Explanation:
Action:
• Check the SCH test point on the D916 (a high level means
a short circuit).
• Check the cable connection between the D916 CPU and the
power board D922.
• Switch off the system and disconnect X5 on the power
board D922. Switch on the system. .
¹ If Error 6 appears, the CPU D916 should be OK.
Check D922, cable connection to the single tank.
¹ If Err 12 is still displayed, replace D916 CPU.
• If the Err 12 disappears, the D916 CPU is OK.
• Then look over the possible problems on the power board
D922, the tube and the wiring.

Error 13 - Voltage in the capacitor bank is low during charge process 0
Error 13 Voltage in the capacitor bank is low during charge process
System status:
Standby
Explanation:
The voltage in the capacitor bank is lower than the voltage
expected from the CPU. The capacitor bank voltage after the
system is switched on is about 400V (VC) and divided on board
100:1 to be monitored from the CPU (Vc).
Action:
• Check the cable connection between the CPU and the D922
(X20).
• Check the VC test point of the D916, and check the voltage
directly in the capacitor bank VC (possible point: HVVC on
D922).
Error 15 - Static short circuit, heating inverter 0
Error 15 Static short circuit, heating inverter
System status:
Standby
Explanation:
Action:
• Check the SCH test point of the D916 (a high level means a
short circuit of the heating inverter).
• Switch off the system and disconnect X5 on the power
board D922. Switch on the system. .
¹ If Error 6 appears, the CPU D916 should be OK.
Check D922, cable connection to the single tank.
¹ If Err 15 is still displayed, replace D916 CPU.
¹ If Err 15 disappears, then the D922 is OK.
• Use Service Program 9 and check the maximum frequency
of the heating inverter (refer to document "Replacement of
parts" SPR8-125.841.10..).
