The Hardware Statistics module displays several internal voltages, temperatures and power
consumption. A value is displayed in red, if the current reading exceeds a pre-determined lower
or upper limit, A value is displayed either as “0” or as “--”, if it cannot be measured.

The controlled parameters are measured with A/D converters and temperature sensors in the
specified subsystem. The measured values are then communicated over the I2C bus to the
power management controller in the DC/DC board for processing, except for CPU voltages,
which are both measured and processed by the CPU board.
Measurement
Description
+ 1.5V CPU Core Voltage (in mV)
+ 1.8V CPU Core Voltage (in mV)
+ 2.5V CPU Core Voltage (in mV)
These CPU core voltages are generated on the CPU
board from the +3.3 V supplied by the DC/DC board.
+ 12 Vsync CPU Voltage (in mV)
- 12 Vsync CPU Voltage (in mV)
These voltages are generated for the ECG and Invasive
pressure analog outputs and marker-out
synchronization pulse. The voltages are measured from
the CPU board.
AC/DC voltage (mV)
The AC/DC voltage is generated by the AC/DC power
supply unit and supplied as an input voltage to the DC/
DC board. The voltage is measured from the DC/DC
board. The AC/DC voltage is “0”, if the patient monitor is
not connected to the AC mains.

.
VSYS voltage (mV)
+15V MOD voltage (mV)
+12V voltage (mV)
+5V voltage (mV)
+3.3V voltage (mV)
These voltages are generated by the DC/DC board and
they are routed via the CPU board to supply power to
other internal subsystems. The + 12 V is also supplied
directly to the backlight LED adapter boardLED backlight
of the LCD display. The +15VMOD voltage is “0”, if E-
module interface board is not installed. VSYS, +12V, +5V
and +3.3V voltages are measured from the DC/DC
board. +15VMOD is measured from the E-module
interface board.

.
+5V REC voltage (mV)
+12V REC voltage (mV)
The +5 V REC and +12 V REC voltages are supplied for
the optional thermal recorder. The +5 V REC supply
voltage is generated in the recorder board by a step-
down converter from the + 12 V received from the DC/
DC board. The + 5 V REC and +12 V REC are measured
from the module frame flex board. These voltages are “-
-”, if recorder is not installed.
+15V MOD PSM voltage (mV)
The +15 V MOD PSM voltage is supplied for the PSM
module. The voltage is measured from the module
frame flex board.
