2 — INSTALLATION & WIRING: Controller
A 6-pin low power Molex connector (J2) is provided for the speed encoder and
electromagnetic brake connections. The mating connector is a Molex Mini-Fit
Jr. p/n 39-01-2065 using type 5556 terminals.
Note: In some applications using a tiller multiplexer, J2 Pins 3 and 6 are used
for a proportional valve instead of an electromagnetic brake.
A 4-pin low power connector (J3) is provided for the 13XX programmer. A
complete programmer kit, including the appropriate connecting cable, can be
ordered; see Curtis programmer manual for further information on the various
programmers available for programming Curtis controllers.
J3 can also be used for the Curtis Model 840 Spyglass display. Although
the display is typically wired directly into Pins 19, 20, and 21 of the 24-pin
connector (J1), it can alternatively be plugged into J3 and unplugged when the
programmer is used. Only Pins 2, 3, and 4 of J3 are needed for the display.
High Current Connections
Six round tin-plated brass studs are provided for the high current connections
to the battery
(B+ and B-), the fuse (F+), and the three motor phases (U, V, W),
located as shown in Figure 2.
The studs are threaded to accept M5 bolts. This simplifies the assembly
and reduces the mounting hardware necessary for the power connections.
Appropriate screws, washers, and cable lugs should be used to provide secure
vibration-resistant connections on all power terminals.
The tightening torque applied to the bolts should not exceed 10 N·m (7.4
ft-lbs). Exceeding this limit could damage the studs’ internal threads, resulting
in loose connections.
