When using CAN lines for communication there must be 2 termination points within the
system. Termination points are explained further in the Configuration section (installation
step 2). What is important at this time is that in order to maximize the efficiency of
communication in your CAN network, you must terminate the two components at the
extreme ends of your main CAN line. This should be taken into consideration as you setup
your EXM system. Each additional EXM component that requires connection to the main
CAN communication line between the two end components will require the use of CAN
Connector Kit (P/N 37221000). The maximum length of wire from the main CAN line is 3ft. and
would be considered a branch (node) off the main CAN line.
CAN Connector Kit:
You may install any of the EXM CAN components that
require the use of a CAN Connector Kit (P/N 37221000) by
plugging the tri-pin CAN connector from the EXM
component directly into the wye connector (Deutsch
DT04-3P-P007) of the CAN Connector Kit. You can also use
the crimp connectors on the mating connector leads to
make your own connection.
Installation Step 1: Mount and Wire All System Components
Monitor –
Before mounting the
monitor, ensure that space allows for monitor to
be rotated and calibrated. Disconnect all electrical connections.
Mount the monitor onto base:
o
Flanged Base
– Mount the monitor onto an appropriate
flat-face flange with 5/8-11 UNC grade 5, carbon steel
or stainless steel bolts & nuts (3” flange or DN80-PN16: 4
bolts, 4” flange: 8 bolts). Seal flange joint with gasket or
suitable flange sealant, and torque bolts uniformly (20
ft-lbs. at a time in a crisscross pattern) to 60-70 ft-lbs.
using blue Loctite 242 or equivalent.
o
Threaded Base
– Thread monitor onto appropriate
threaded flange using Loctite 592 or equivalent thread
sealant. Tighten using a strap wrench on the hex
portion of the monitor base.
If the monitor will use a CAN line to communicate with other EXM components,
connect plug 1 leads to the appropriate CAN line leads.
o
If the monitor will use RF (radio frequency) to communicate with other EXM
components, no preparations are required. The monitor is already RF enabled.
o
If the CAN leads will not be used, replace wires with appropriate plugs.
Supply power to the monitor by connecting the red and black leads from the 6 pin
connector to an appropriate power source. Install a 20 Amp fuse into the positive
power lead for a 12V system (10 Amp for 24V system) to protect the monitor electrical
components.
Refer to the respective plug figures for information on the plugs’ pins.
