You can
install only one type of device or measurement point (PDT101 transmitters, analog
input channels, safety barriers, or galvanic isolators) per row in the
cabinet.
In cabinet models with 5 to 8 data
loggers, you need 2 serial port servers.
One serial port server controls
the traffic of maximum 4 data loggers.
Make sure to number the
data loggers as well as the cable sets and wires in the Analog Wiring Set before you
install and connect them.
DL4000 data loggers are
delivered with default factory settings. This applies both to the factory-installed
data loggers and the ones delivered as spare parts. For instructions on configuring
measurement units and scaling in the data loggers, see the Vaisala viewLinc
Enterprise Server User Guide for your viewLinc version, available at
www.vaisala.com/viewlinc.
Follow the steps below to install terminal blocks for analog input channels as new devices to an empty DIN rail in CAB100B.
You can apply this installation procedure also when expanding the number of analog input channels in the cabinet. For example, to increase the
number of analog input channels on a DIN rail from 4 to 12, order 2 Analog Wiring Sets and 2 data loggers.
Switch off mains power and the circuit breaker located inside the cabinet.

Circuit breaker
Only when expanding the analog terminal block installation on a DIN rail:
Disconnect the analog channel 24 V DC power cable connector from the power block,
located on the right-hand side of the cabinet.
Remove the cable duct cover below the empty DIN rail reserved for the analog terminal block.
Remove also the long vertical cable duct cover in the middle of the cabinet.
Assemble the new analog channel terminal block.
See the instructions in Vaisala CAB100 Assembling Analog Channel Terminal Block Technical Note (M212262EN),
included in the Analog Wiring Set (ASM213078SP).
Mount the analog channel terminal block on the DIN rail.
Assemble the data logger holder.
Place the data logger in the logger holder.
Fit the cover into place.
Tighten the screw by hand.
Connect the logger data cable to the RS-232 serial port in the data logger.
Use a small flat head screwdriver to tighten the screw attached to the connector.
Mount the data logger on the DIN rail, preferably at the right-hand end of the rail.
Rest the logger holder locking mechanism on the DIN rail and push down firmly. This will click the device into place.
Connect the logger data cable to a free port in the serial port server.
Connect the analog channel terminal block to the data logger and to the 24 V DC power
block, as shown in 10 to 12 below.
Use the cables in the Analog Wiring Set
(Vaisala item code: ASM213078SP).

Insert any extra length of wire into the cable ducts and replace the cable duct covers.
Only when expanding the analog terminal block installation on a DIN rail:
Reconnect the 24 V DC power cable
connector (disconnected in 1.b) in the power block.
Reconnect power in the cabinet.
Switch on the circuit breaker.
Switch on mains power.
1 Required only when introducing analog input channels as new devices in
CAB100B.
2 You need 3 Analog Wiring Sets (Vaisala item code: ASM213078SP)
to assemble a 12-channel terminal block.
