Protective measures

•Observe the protective measures described in Register 1 of the UROSKOP D Logbook.

•Prior to performing any service work on the generator, switch it off with the power OFF switch on D200.

•In order to deenergize all parts of the system, set the system switch to the OFF position.

CAUTION

With the generator switched off, line voltage is still present at transformer T1 and fuse panel D200 (refer to wiring diagram X2075-11).

After switching off the generator, approx. 600 V DC voltage are still present at the inverter; indicated by LEDs V8 and V9 on board D250 (see X2075-17).

Within approx. 1 1/2 minutes the voltage drops to 0 V; the LEDs go out at approx. 30 V.

•To prevent unintentional release of high voltage or radiation, set switch SS on D200 to OFF (no actuation of the inverters).

•Remove or insert boards only with the generator switched off. When doing so, observe the ESD guidelines (see TI 219, Info RA.5. RA0-000.012.19... on microfilm).

•On D211: switch S1 INT OFF (position 2).

•On D200: switch SS OFF.

Measuring the line voltage

•Remove fuses F1, F2 and F3 from the fuse board in M16 (generator).

•System contactor ON.

•Measure the line voltage.

The voltage must correspond to the values indicated in the test certificate (logbook, Reg. 3).

Checking the on-site emergency shutdown button

•Actuate the emergency shutdown button installed by the customer. The entire system must be disconnected from the power line.

•System contactor OFF.

Siemens AG	Register 4	RLL5-310.034.04	Page 1 of 4	UROSKOP D3
Medical Engineering		Rev. 04 12.98	TD PS 24

Checking the phase connection

•Check the correct phase connection of the power lines at M16.F1, F2, F3 (X2075-11), using the rotating field instrument:

•In M16, remove the cover from the fuse holders.

•Connect the3-phase field rotation meter to the lower connections of F1, F2, F3 (on the side of the power supply).

•System contactor ON.

•Perform the measurement.

•System contactor OFF.

•Disconnect the rotating field instrument.

Measuring the internal line impedance

•Measure the internal line impedance at M16. F1. F2. F3 (X2075-11):

-Connect the internal line impedance meter between two phases of F1, F2, F3 (at the lower connections of the fuse holders).

-System contactor ON.

-Perform the measurement.

-System contactor OFF.

• Record the measured values in the test certificate (logbook Reg. 3)

•Enter the measured values into the ”LINE PARAMETER” module of the system programming.

Important: In order to obtain the full generator power, the internal line impedance measured may not exceed the following values:

	Uline	max. Rline withPOLYDOROS		measured
		SX 50	SX 80
	400 V	0.18 Ohm	0.12 Ohm
	440 V	0.20 Ohm	0.16 Ohm
	480 V	0.24 Ohm	0.20 Ohm

Internal line impedances of > 250 mOhm reduce power. Refer to RX63050.034.05.01.05... Configuration ”LINE PARAMETER”

•Reinsert fuses F1, F2 and F3.

•Reattach the cover.

		Rev. 04 12.98	TD PS 24	Medical Engineering

Checking unacceptable ground connections

(connection between and 0VL ).

•Disconnect the connection lead between the upper and lower grounding bus (in the generator power cabinet).

•Using the multimeter, measure the resistance between and 0VL: The measured resistance must be approx. > 50 kΩ.

•Reconnect the upper and the lower grounding bus.

Switching on the generator

•System contactor ON:

-LED V26 (via fuse F11) must light up on fuse board D200. In case of an error, check the fuses in M16 and on D200 (X2075-11 and 12).

•Generator ON:

-On fuse board D200, press key and actuate button .

-The LED’s must light up as follows on the service panel of D211:

The +5 V, ± 15 V, +24 V supply voltages are immediately present.

If the +5 V voltage is missing, the generator is disabled.

In this case, check the fuses on D200 (X2075-12). All LED’s on D200 must light up.

-Following connection of the intermediate circuit (activation of charging contactor and power contactor), LEDs V9 and V8 on board D250 must light up (X2075-17).

				A DC voltage > 500 V is applied to the intermediate circuit.
	CAUTION

-Following correct initialization (after approx. 10 sec.), the following LEDs must light on the service panel of D211:

( ) ( ) TU1 (after system programming) GEN-OK,+24 V, +15 V, -15 V, +5 V
