14 Control output 0-10V
The voltage is used to control external power sources. The source is normally connected to the channel PF2
(normally a motor driven variac transformer). The voltage level is selectable via the operating facilities of the
UCS 500N. The voltage level can also be selected within the service menu under the fu
nction „setup.
This output is not mounted on UCS500N5E and UCS500N5V.
15 Safety circuit
The test can only be started if the security circuit is closed. If the circuit is opened during a running test the
simulator will be switched off immediately.
14 Mains selector
Selection of 115V / 230V
17 Power on switch
The switch is part of the mains filter. Mains fuses are part of the filter. (230V / 2 A and 115V / 4 A)
18 Fuse of the high voltage power supply
The high voltage power supply is protected by this fuse „F3“. In case that no high voltage is generated but the
control unit works properly this fuse shall be checked.
19 USB interface
USB interface “USB B” connector. For data-transfer a USB interface is available. The internal RS 232 interface
is converted to USB standard. Therefore the user must set the same baud-rate in the device and control
software.
Using the USB interface may cause EMC problems during burst tests at the computer or notebook side of
the communication line. Therefore a high quality USB cable (USB 2.0 standard) shall be used.
20 Parallel interface GPIB / IEEE 488
IEEE 488 interface with IEEE connector
21 Remote control connector CN
External coupling devices are controlled via this remote control connector.
22 Fail detection FAIL 1 EUT control (TEST STOP
Grounding this input will cause a complete stop of the running test procedure. (+15V to ground) The test must
be completely restarted.
23 Fail detection FAIL 2 EUT control (TEST PAUSE
Grounding this input will cause a break for the running test procedure (+15V to ground).The test will be
continued when the input is no more connected to ground.
