III.MOUNTING INSTRUCTIONS

See Figure 7 on page 6. Note: Figure 7 is also supplied as a separate drawing.

WARNING! Make ! sure all power is disconnected from the KBMG before proceeding.

A.Removing the KBMG FingerSafe Cover – If a finger-safe cover is not installed on the KBMG, proceed to Section III B. If a finger-safe cover is installed on the KBMG, remove the two (2) socket head 5-40 X 1/4” screws located at the rear of the KBMG using the supplied 3/32” hex key. Also, remove the two (2) 6-32 X 13⁄4” screws located on either side of Terminal Block TB1 of the KBMG. See Figure 8.

B.Removing Terminal Block TB1 from the KBMG – Remove Terminal Block TB1 from the KBMG by rocking it back and forth or using a flat blade screw-

driver to gently pry it off. The removed terminal block will not be used and may be discarded. See Figure 9.

C.Modifying the KBMG Finger-Safe Cover – Once the KBMG finger-safe cover is removed, it has to be modified to accommodate the KBMG Multi-Speed Board. Cut out the finger-safe cover panel at seven (7) places as shown in Figure 10, on page

D.Installing the KBMG Finger-Safe Cover – Once the KBMG finger-safe cover has been modified, it can be installed onto the KBMG. Initially, use only the two (2) 5-40 X 1/4” socket head screws, using the supplied 3/32” hex key. Do not over tighten these screws or damage may result to the KBMG finger-safe cover. See Figure 6 on page 6.

Note: All jumpers on	FIGURE 10 – REMOVING KBMG FINGER-SAFE
the KBMG must be set	COVER PANEL
before installing the KBMG
finger-safe cover.

E.Installing the KBMG Multispeed Board onto the KBMG – The terminal block

located on the bottom of the KBMG Multi-Speed Board plugs onto the six (6) header pins where TB1 was removed from the KBMG. The two (2) holes on the back of the KBMG MultiSpeed Board snap onto the finger-safe cover. Use the two (2) 6-32 X 13⁄4” screws, that were previously removed, to secure the

KBMG Multi-Speed Board	KBMG Finger-Safe Cover. Remove Panel
to the KBMG. Do not over	(cut 7 places) to Install KBMG Multi-Speed Board.
tighten these screws or
damage may result to the

KBMG Multi-Speed Board and the KBMG. See Figure 7, on page 6. Installation is now complete.

						PS 4

A.Preset Speed Connection – Preset speed range, direction, and speed are selected by making a contact

closure between Terminals COM and either PS 1, PS 2, PS 3, or PS 4 of Terminal Block TB1. See Figure 11.

opened, the control will stop. Note:

KBMG Multi-Speed Board Jumper J1

must be installed or a connection must be made between Terminals EN and COM of Terminal Block TB1 in order for the KBMG Multi-Speed Board to operate. See Figure 12, on page 10.

C.Tach-Generator Connection – If a tach-generator is to be used, wire a 7 Volt (or 50 Volt) DC per 1000 RPM tach-generator to the KBMG MultiSpeed Board, connect the positive (+) side of the tach-generator to Terminal T2 of CON2 and the negative (-) side of the tach-generator to Terminal T1 of CON2. Note: If the positive (+) and negative (-) tach-generator connections are not as described above, the motor will run at full speed only. See Figure 13. (Note: Refer to the KBMG instruction manual for tach-generator feedback operation.)

V.OPERATION

After the KBMG Multi-Speed Board has been properly setup (jumpers and trimpots set to desired positions and wiring completed), the startup procedure can begin. If AC power has been properly brought to the control, the power on (PWR) LED, on the KBMG, will illuminate. Select a preset, as described in Section IV A, on page 10. The motor will begin to run at the preset speed selected.

11

VI. TRIMPOT ADJUSTMENTS (Each Preset)

The KBMG Multi-Speed Board contains trimpots which are factory set for approx. 50% of base motor speed. Readjustment of the trimpots will be required in order to tailor the control for a specific application. If the HI and LO jumpers have been changed in accordance with Figure 4, on page 4, the trimpot ranges will also change. Readjust trimpots as shown in Figure 14.

WARNING! If adjustments are made with main power applied, an insulated ! adjustment tool must be used and safety glasses must be worn. High voltage exists in this control. Fire and/or electrocution can result if caution is not exercised. Safety Warning, on page 1, must be read before proceeding.

Preset 1, Preset 2, Preset 3, Preset 4 – Sets the speed of the motor (within the speed range selected with both Jumpers HI and LO, as described in Section II B, on page 4). For a higher speed setting, rotate the selected preset trimpot clockwise. For a lower speed setting, rotate the selected preset trimpot counterclockwise. See Figure 14.
