6U VME 6023 Crate Series

Intelligent NIM / CAMAC Fan Tray UEL03 / CEL03
CERN spec. conform fan tray unit equipped with alphanumeric monitoring and three long life
DC axial fans, either with frontal or bottom air entry (400m³/h or >540m³/h airflow). Static
pressure up to 8 mm H 2 O column. MFOT (Maintenance Free Operation Time) > 65 000h / 40°C.
Fan speed is variable from 1200 to 3000 rpm
The monitoring can be toggled to display: voltages, currents, fan speed, temperature of
incoming air, total power dissipation by inserted modules, network address (if installed). Displayed
currents are scaleable to obtain true values. In case of malfunction the type of error will be
displayed.
Additional LED information is showing:
Status (Green):
all values inside tolerance
Fan fail (Yellow):
one or more fans fail
Over Heat (Yellow): power supply overheated
The fan tray monitoring can be set to Programming Mode. This mode allows programming of
all key functions and for 336-power supply values like current limits, status thresholds, etc.. The
Status Signal is superposed by an additional pulse modulated information (from PS/CS 336 only)
to extend the CERN spec. monitoring and control.
Different Remote Control Interface are installable.
1. CAN-bus
2. HS CEANET
3. IEC Bus
UEN 01 Front View
CAN-bus Remote Control and Monitoring Software can control up to 126 crates within a network.
The user can control and program remotely every crate parameter and On/Off via the interface
such as:
Crate Identification
All voltages, currents and temperature, status signals
Over- under voltage trip off points and current limit adjustment (with 336 only)
Average fan speed and display of every single fan
Configuration and adjustment (for service and maintenance)
CERN spec. monitoring connector
CERN Spec. Monitor Connector
Important signals of the »M« power supplies have been wired to the 36 pin ribbon connector.
This connector monitors:
Power fail
Overload
Overheat cut off
Status (pot. free contact)
All output voltages (Voltage outputs are internally protected by resistors against short
circuit.)
Disable signal prevents cut-off function
Inhibit signal keeps DC off and stops acoustic alarms
CE conform Crate versions / CE conform mains connection
CERN spec. wired bins allow to switch crates on and off via the mains switch at the fan tray.
Current rules as CE60950 and UL1950 claim for primary to secondary isolations, which are not
considered in the appropriate CERN specifications. Therefore WIENER formed a compromise to
fulfill CE and UL safety restriction as well as CERN specifications by separating the mains wiring.
NIM Compact Slot Power Supply UEP 15
Plug in power supply for use in UEN 04 bins or for powering every non-powered extant NIM bin.
UEP 15 features all 6 voltages, stabilized by adjustable monolithic voltage regulators, on rear
NIM connector with standard NIM pin out. Ground and 6V outputs are spliced-wired to two pins
for minimized voltage drop.
UEN 04 Portable
The integrated blower cools heat sink, components and the toroid transformer. Voltage regulators
and transformer are protected against over temperature. Over- under voltage detector (limits ca.
+/-3% of nominal voltages) activates mains cutting relay (red signal “bad status” at front panel).
Mains voltages: 100, 115, 225, 240VAC by use of different internal transformer taps.
Optional CAN-bus interface for DC voltage monitoring and remote on/off via rear 9 pin sub D
connector
