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
pipe 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.
Caution:
Do NOT use motors or discharge as leverage to tighten monitor.
Warning:
When installing the monitor on a raised face companion flange, it is critical
that the bolts be tightened uniformly to prevent misalignment of the monitor relative to
the flange or valve. If the monitor becomes misaligned, the base flange will fracture and
fail when the bolts on the “high” side are tightened.
