4. Power Equipment
1) SB TYPE (Parking Facility)
·Horizontal Type ⇨ Low Grade Type: To shorten the braking time, use S/W to operate Low Grade;
otherwise use High Grade.
·Vertical Type ⇨ High Grade Type (Contactor-less Power System): Since the system with
Contactor-less Power System, you still get the prompt braking time with High Grade. No S/W
makes connection simple.
2) HB TYPE
·Low Grade Type: To shorten the braking time, use S/W to operate Low Grade; otherwise use High
Grade.
5. Gap
1) Although spacing is optimized at the factory, a long period of use may result in enlarging the space
between ARMATURE and MAGNET due to wear of the lining, which will reduce braking ability.
2) Measure the space between ARMATURE and MAGNET by inserting the GAP GAUGE in 3 to 4
locations around the lining. And the gap must be equal in size.
3) Gap Adjustment Method: After measuring, if the gap is larger than allowable, then use the space
adjustment nuts and insert the GAP GAUGE at 3 to 4 locations around the lining.
6. Manual Release System (SB TYPE)
1) Horizontal type: Loosen the lever handle during standard operation. If manual release is
needed, push the lever handle clockwise.
2) Vertical type: Because the system uses non-excitation brakes, separate the lever handle with
the manual lever during standard operation. If manual release is needed, push the manual lever
toward reducer.

■■■Selection (Technical Data)
1. Selection Sequence
1) Gear Ratio
Select the Gear Ratio according to the required output rpm by the following equation.
2) Output Torque
Calculate output torque from load torque. If load torque is variable, calculate maximum torque.
Table 1. Service Factor
3) Motor Selection
Select Motor HP based on the required torque and ratio from "RP-SERIES DATA SHEET."
4) Moment of Inertia (GD2
)
When there are frequent starts and a large moment of inertia, they must be considered due to the
generation of high impact torques.
① Calculate the GD2
which can be found on page 6
② Calculate Moment of Inertia (GDL
2
) for high speed side
③ Based on the selected motor HP, find GDM
2
(Moment of Inertia at geared motor's side) value from Table 2
Table 2. Geared Motor GDM
2
④ Calculate "Z" value.
⑤ Select proper service factor(SF2) from Table 3 based on the duty cycle and "Z" value.

■■■Recommendation
1. Installation Requirements
1) Ambient Temperature: -15C - 40C
2) Humidity: Below 85%
3) Altitude: Below 1,000m
4) Installation Location: Indoor
5) Jobsite's Environment: Good Ventilation with no corrosive nor explosive gas
2. Connection Method
A. Direct Connection
HICO geared motor is optimized in direct connection and recommends flexible coupling if possible.
B. Indirect Connection with geared or chain sprocket:
1) Gear and Chain sprocket
When mounting geared or chain sprocket, select the diameter of geared or sprocket by using the
equation below so that load is acting on the middle of output shaft. Insert fully to the protrusion part of
the shaft.
2) Chain Length
If chain is used, make sure it is not loose.
If a different connection method, other than above ways, or intensive duty cycle (frequent starts and
stops) is required or the moment of inertia(GD2
) is too high, please contact HICO.
3. Counter Rotation
In case of changing rotational direction, stop the rotation completely with brakes and then run it in the
reverse direction.
4. Installation
1) Make sure to install the unit horizontally.
2) Contact HICO if installing on high angle is necessary
■■■Selection of Lubrication
1. Lubrication
Fill up the grease to middle of oil level gauge. If lubrication level is too high or too low, the gear and the
bearing will be damaged.
2. Changing Lubrication
Due to the abrasion dust, change the lubrication within 500 hours of initial operation. Change it every
2,500 operation hours after.
