G-coded Electrical Connector
(Units where the electrical connector type
has a code starting with “G”, e.g., G01.)
Units specified with a G-coded
connector use a Turck
®
brand,
versafast
style, BSMK type, con-
structed of polyurethane with a
nylon coupling nut. The connector
is over-molded onto an electrically
shielded, PVC-jacketed cable.
The pin contacts for the electrical
connection are gold-plated for perfor-
mance and corrosion resistance. The
connector is physi cally “keyed,”
making it easy to connect to a recep-
tacle. Press it into a receptacle and
turn the threaded coupling nut to
draw the connector and recep tacle
together until finger tight. G-coded
connectors to pigtail mating cables
are available. See the
Ordering
Infor mation
Section
of this
user guide.
The following pin diagram and
Table 2 detail the wire connections
for the flow controller type with
G-coded electrical connector.
Mandatory Connections
2-Red/Pin R and 8-Black/Pin E
wires must be connected according
to Table 1, Table 2 and the
Wiring
Diagram
on page 16. The set-
point must also be connected to
10-Tan/Pin U wire (4–20 mA
setpoint) and 12-Gray/Pin S
wire (common setpoint) or to
11-Pink/Pin G wire (voltage set-
point) and 12-Gray/Pin S wire
(common setpoint). Connect
9-Green/Pin J (re-zero input) to
switched, normally open 24 VDC
±10% main power supply in order
to have the same ground as the
8-Black/Pine E (ground).
NOTE:
The 24 VDC connected to
rezero must be the main power
supply in order to have the same
ground as 8Black/Pin E. See the
Maintenance Section of this user
guide for rezero instructions.
Consult Entegris with any questions
about electrical installation.
Unused Connections
The 6-Violet/Pin O and 7-White/Pin P
wires are for factory use only. Do not
connect to power supply or ground.
These wires must remain discon-
nected.
