*4'
cable used to interface GFC IIA regulator to system. Complete
with 24 pin connector.
• Heavy duty steel enclosure used to mount GFC IIA on site or in control
cab. Can also be used with GFC, GFC II, lSSD-1, GMB-A and GMB-B.
** In some areas of the country, UL requires this cover to be used. The
bracket protects all of the external potentiometer knobs from accidental
bumping once the GFC IIA is adjusted properly.
~ Kit includes all external resistors, capacitors and relays necessary
to interface GFC IIA or other generator field control regulators to a motor-generator
set. |
GFC IIA replaces U.S. Elevator (Varitron) SSD1, Elevator Industries
GMB (Model A), Reliable Elevator GFC, GFCII. Also replaces E-I
GMB (Model B) with minor wiring change.
NOTE: Also used in variable voltage controllers made by numerous
regional companies, such as, Virginia Controls, Vertitron, Mid-American,
Century, etc. See full specification below and an expanded data
sheet.
Supplies generator shunt field, brake excitations. Provides consistent,
smooth, stepless acceleration, and stopping functions, and is adaptable
to all new or modernized elevator installations up to 350 FPM.
Incorporates the following independent controls:
• High speed
• Acceleration
•
Deceleration – one floor run
•
Deceleration – multi-floor run
• Approach speed
• Level speed
• Relevel speed
• Motor field weakening
Solid state design. Furnishes built-in protection from loss of
motor field.
All units undergo high-temp environmental testing and burn-in to
minimize problems caused by infant component mortality after installation
in the field. (Box and cable assembly not included.) Technical Specifications:
