INFICON BCG450-SP ATM to Ultra-High Vacuum Triple Gauge (Profibus) - Manual (Page 2)

Sensor Cable Connection
For reasons of compatibility, the expression "sensor
cable" is used in this document, although the pres-
sure reading of the SD-type gauge is normally
transmitted via the DeviceNet interface.

shielded
Cable length, (conductor cross
section per conductor) ≤35 m (0.25 mm 2 )
≤50 m (0.34 mm 2 )

Switching functions 2
Setpoints adjustable via
potentiometers (Setpoints
A and B), one floating,
normally open contact per
setpoint
Relay contact rating ≤60 VDC, ≤0.5 ADC
Atmosphere switching function → [2]
Gauge identification 42 k Ω between Pin 10
and Pin 5 (sensor cable)

Operation
Caution
Caution: data transmission errors
The attempt to operate the BPG450-SD with the
RS232C interface causes data transmission
errors.
The BPG450-SD must not be operated with the
RS232C interface.
Operating Software
Before the gauge is put into operation, it has to be configured
for the DeviceNet. A configuration tool and the device speci-
fic EDS file (Electronic Data Sheet) are required for this pur-
pose. This software can be downloaded via internet
(
→ [5]).
Node Address Setting
Set the node address (0 … 63
dec
) via the
"ADDRESS" "MSD" and "LSD" switches
(default 63
dec
). The node address is polled
by the firmware when the gauge is
switched on. If the setting deviates from
the stored value, the new value is taken
over into the NVRAM. If a setting higher
than 63 is made, the previous node ad-
dress setting remains valid.
If the MSD switch is in the "P" position, the
node address is programmable via the
DeviceNet (
→ [3]).
Data Rate Setting
By means of the "RATE" switch, the data rate can
be set to 125 ("1"), 250 ("2") or 500 kBaud ("5")
(default 500 kBaud).
If the switch is in any of the "P" positions, the data
rate is programmable via the DeviceNet (
→ [3]).
Adjusting the Gauge
Gauge adjustment is carried out automatically, no manual
adjustment is required (adjustment of the atmosphere sensor
→ [2]).
Adjusting the Switching Functions
→ Adjustment and settings.
Status Lights
"STATUS MOD" (gauge status):
Light status Meaning
Dark No supply
Flashing
red/green
Selftest
Green Normal operation
Red Non recoverable error
Flashing red Recoverable error (e.g. missing DeviceNet
power supply).
"STATUS NET" (network status):
Light status Meaning
Dark Gauge not online:
– Selftest not yet concluded
– No supply,
→ "STATUS MOD" light
Flashing green Gauge online but no connection:
– Selftest concluded, but no connection
to other nodes established
– Gauge not assigned to any master
Green Gauge online; necessary connections
established
Flashing red One or several input/output connections in
"time out" status
Red Communication error. The gauge has de-
tected an error that impedes communica-
tion via the network (e.g. two identical node
addresses (MAC ID) or "Bus-off")
