Procedure
• Call up Test program 16, Adjustment 11.
• At the BIPOLAR output of the ICC, the ERBE bipolar Testbox for the bipolar automatic starter (EE
20100-017 ) or appropriate fixed resistors (1.2 kOhm and 2.5 kOhm with a capacity of 15 watts as
well as 18 kOhm, 1 watt) is connected via the EE bipolar original cable.
• With a resistance of 2.5 kOhm (socket 1–2), a value of 25 must be displayed in the AUTO CUT field.
(Display = resistance divided by 100). The setting of the switch-on threshold with PT11 on the PCB
control board (slot J3) proceeds in such a way that, at a load resistance of 2.5 kOhm, the display in
the AUTO COAG 2 field changes from “OFF” to “ON”.
• Now the short-circuiting monitor is set by connecting a 6 ohm resistor (capacity = 0.5 watts) to the
BIPOLAR outlet. Then, the display »rLo« appears on the AUTO COAG 1 display. Using TP12 on the
PCB control board J3, the display is set to a measurement value of 100 in the AUTO CUT display.
• Testing the shutdown response: To do this, exit Test program 16 briefly by selecting Test program 0.
The ICC operates in the normal mode. Switch on AUTO START 1. Set the bipolar power to 1 watt.
The BIPOLAR outlet is connected to sockets 1 and 3 on the ERBE Testbox and thereby charged with
1.2 kOhm. The BIPOLAR generator must automatically be activated after the delay time. Now press
pushbutton 1 on the Testbox. This raises the capacity resistance to 18 kOhm. The BIPOLAR generator
must now shut down.
• This test must be repeated at the power settings 20 watts, 40 watts, 50 watts (or without AAMI
standard up to 120 watts).
