Operating Instructions Chassis Monitoring Module (CP3-CMM1)
31.01.2003, D0.5 2
1 Functional Description
The CMM monitors up to four different dc voltages
continuously for exceeding the high- or low-end of
voltage tolerance. An error signal is generated if
tolerance is exceeded. The error status can be displayed
by LEDs or at the HTML page. There are two additional
dc-voltage inputs available for the voltage-range +/-
24Vdc. All voltages are system ground based.
Up to seven temperature sensors can be connected
direct to the unit. Four additional temperature values are
transferred from the FCM. A temperature fail is
generated if one of the temperatures is higher than the
adjustable temperature alarm level.
There are 16 digital inputs. They can be used to identify
power-good-signals, shelf-address, VME-signals and
customized applications.
Ten digital outputs are available for customized
applications. Four signals are open-collector isolated by
opto-couplers. Six signals are TTL-compatible non-
isolated.
The CMM is able to communicate with the fan control
module (FCM). One connector ensures direct connection
to the FCM, power supply and communication. The
temperature values of FCM and the speed of fans are
transferred to the CMM.

Input Signal Monitoring
The following signals are being monitored
continuously:
Voltage monitoring
Up to 6 DC voltages are monitored continuously.
The status of +3.3V, +5V, +12V, -12V is signaled
by the green/red LED output (within tolerance
/out of tolerance). The condition of the +24V, -
24V is signaled by default setting by digital
outputs 6 and 7 (see chapter 5).
+ 12,0 VDC Tolerance: ± 0.6V
+ 5,0 VDC Tolerance: ± 0.25V
+ 3,3 VDC Tolerance: ± 0.25V
– 12,0 VDC Tolerance: ± 0.6V
+ 24,0 VDC Tolerance: ± 2.4V
– 24,0 VDC Tolerance: ± 2.4V
NTC temperature sensors
Up to 7 NTC temperature sensors can be
connected to the CMM. The number of
connected NTCs must be registered manually
in the configuration mode of the CMM (see
chapter 5). Two temperature alarm thresholds
(20°C...70°C) can be set. If the CMM is
connected to the FCM, the NTC with the highest
temperature reading of both modules gives the
fan speed.
