OUTPUT WIRING
The Badger
®
M-4000 Meter converts liquid fl ow into
electrical signal(s). With proper output wiring and amplifi er
programming, the signal(s) are sent to, and used by,
processing equipment used in operations or other
procedures.
NOTE: Output wires and terminals are the same for meter
mount or remote mount meters
Output wiring requires 18 to 22 AWG maximum, shielded
wire (not supplied). Signal wire insulation temperature class
should exceed the maximum temperature where installed
(typical, 185°F, 85°C).
Use conduit and conduit fi ttings (not supplied) rated for Class
I, Div 1 hazardous locations.
Output Wire Connections
·
Properly trained personnel must perform all
installation and/or repair procedures.
·
Disconnect power to the unit before attempting any
installation or maintenance.
To connect control signal wires:
1. Remove the connections chamber cover. If necessary,
use a strap wrench.
2. Remove the two terminal block wire port access screws.
3. Connect output wires to processing equipment.
4. Group and place output wires in conduit. Position conduit
at amplifi er terminal block wire ports.
5. Connect conduit to control output signal wires ports.
6. Run output wires through wire ports, into amplifi er
terminal chamber.
7. Strip output wires back ¼ inch (6mm).
8. Connect output wires to terminals (see below).
NOTE: Use twisted pair shielded wire for all output wiring.
Belden #1266A or equivalent.
