PRO-GH and PRO-GHC heavy-duty jackshaft operators are designed for large commercial and industrial doors provided that
doors are driven by a drive shaft. Model PRO-GH is essentially the same as model PRO-GHC with the exception that the PRO-
GHC operator has a reinforced frame and pillow block bearings on reducer drive shaft.
STANDARD OPERATOR WEIGHT
: PRO-GH (100-120 Lbs.) PRO-GHC (120-150 Lbs.)
MOTOR
: Continuous duty 1725 RPM industrial type motor. Full overload protection.
- Horsepower range for PRO-GH: 1/2HP, 3/4HP, 1HP, 1.5HP (3-phase & 1-phase), 2HP , 3HP, 5HP (3-phase only)
- Horsepower range for PRO-GHC: 1/2HP, 3/4HP, 1HP, 1.5HP (3-phase & 1-phase), 2HP, 3HP (3-phase only)
- Voltage:
115V 1-phase (60Hz)
230V 3-phase (60 Hz)
220V 1-phase (50Hz)
230V 1-phase (60Hz)
460V 3-phase (60Hz)
380V 3-phase (50Hz)
575V 3-phase (60Hz)
REDUCTION
:
Primary: Heavy duty worm gear reducer 40:1 – 44:1 reduction
Secondary: #50 chain and sprockets from operator to door shaft
OUTPUT SHAFT SPEED
: 40-43 RPM
BRAKE
: Solenoid actuated drum and brake shoe braking system to prevent coasting and maintain door position.
WIRING TYPE (3 OPTIONS)
:
Option 1:
Full Feature logic board Smart 10.0 (UL325 (2010) compliant)
. Note: Micanan compatible primary entrapment
device must be connected for B2, T or TS (momentary or timer activation on close) feature.
Option 2:
Relay logic controls with Interface Module (UL325 (2010) compliant
). C2 Standard factory wiring (constant
pressure on close, momentary contact on open and stop). If momentary contact on close (B2) wiring is desired,
move “white” wire from terminal #6 to terminal #3. Note: Micanan compatible primary entrapment device must be
connected for B2 (momentary activation on close) or for T (timer to close) feature.
Option 3:
Standard relay logic controls (not UL325 2010 compliant, not available in US)
C-2 Wiring constant pressure
on close, momentary contact on open and stop. NOTE: If momentary contact on close (B2) wiring is desired, move
“white” wire from terminal #5 to terminal #3.
TRANSFORMER
: 24VAC control circuit, supplies power to drive control relays with 15VA power available for external
devices.
LIMIT ADJUSTMENT
: 4 micro switches that control door travel. These limit switches are activated by fully adjustable screw
type cams.
EMERGENCY DISCONNECT
: Floor level cable disconnect system with electrical cut-out feature allows person to manually
operate door by chain hoist in case of emergency.
