9.6 Optional Overload Protection with KBAP-240D (Part No. 9106)

The KBAP-240D

is a multipurpose DC

Current Sensing Relay and Overload

Protector. It is specifically designed for use

with DC motors and speed controls from 1/8

- 3 HP. KBAP-240D

operates by sensing

current in the armature circuit. When the

preset level is reached, the output relay

(RY1) trips. An adjustable time delay (0.2 -

15 secs.) is incorporated, which eliminates

nuisance tripping. Manual or automatic reset

is provided at the user's option along with a

LED, which indicates when the preset

current level has been reached. When an

overload occurs, the KBAP-240D

can be

used to shut the system down, sound an

alarm, or initiate corrective action before

damage occurs. Refer to Figure 12.

10 OPTIONAL ACCESSORIES

• Auxiliary Heat Sink (Part No. 9861): Doubles the horsepower rating of the control.

• Barrier Terminal Accessory Kit (Part No. 9863): When used with the Auxiliary Heat Sink, it converts the

quick-connect terminals of the control to a barrier terminal block.

• Barrier Terminal Board (Part No. 9884): Converts the quick-connect terminals of the control to a barrier

terminal block. Contains PC board mounted line and armature fuse holders (fuses supplied separately).

Plugs onto the quick-connect terminals of the control.

• SI-5 Signal Isolator (Part No. 9443): Provides isolation between non-isolated signal sources and the

control. Plugs onto the quick-connect terminals of the control.

• Dial Plate & Knob Kit (Part No. 9832): Provides indication of the Main Speed Potentiometer position

(0 – 100 %).

• AC Line & Armature Fuse Kit (Part No. 9849): Provides fusing for the AC line input and armature.

Includes wired fuse holders and mounting screws. Fuses supplied separately.
