2 — INSTALLATION & WIRING: 1207 Controller
ADJUSTMENT PANEL
The adjustment panel is located on top of the 1207 controller, under a sliding
protective cover. The panel provides access to a set of adjustable potentiometers,
and also contains the Status LED and a connector for the handheld programmer.
Manually Adjustable Potentiometers
Five screwdriver-adjustable potentiometers (“trimpots”) allow manual
adjustment of the main and plug current limits, acceleration rate,
maximum creep speed, and maximum speed (labeled “
LOW
”), as de-
scribed in Section 3. The trimpots can be enabled or disabled at the
factory; if they are enabled, MultiMode™ operation is not available.
NOTE
: To adjust any of these parameters electronically with the pro-
grammer, its potentiometer must be set to “
OFF
.”
Programmer Connector
An RJ11 modular connector is provided for the handheld programmer.
The mating cable is supplied with the programmer.
Status LED
The LED displays flashing codes to indicate controller status; the codes
are listed in Section 5.
