User manual KB ELECTRONICS APRM-PC

[. . . ] It is the responsibility of the equipment manufacturer and individual installer to supply this safety warning to the ultimate user of this product. (SW effective 11/92) This control contains Start/Stop and Inhibit circuits that can be used to start and stop the control. However, these circuits are never to be used as safety disconnects since they are not fail-safe. The input circuits of this control (potentiometer, Start/Stop, Inhibit) are not isolated from AC line. [. . . ] Note: This should be the same setting as the Jumpers J2A and J2B are set for on the KBPC main board which should correspond to the correct AC line input voltage. Refer to the KBPC-240D Installation and Operating Instruction Manual for complete information. TABLE 2 ­ GENERAL PERFORMANCE SPECIFICATIONS Input AC line voltage ­ 50/60 Hz . 115/230 Maximum number of run/brake or forward/reverse operations per minute* . 0 ­ 50 *Based on a one (1) minute braking time. Mount the APRM®-PC on the 4 bosses located on the inside cover of the KBPC-240D using the four (4) # 6-32 screws provided. Position the APRM so that the brake resistor is toward the bottom of the cover. Be sure not to trap any wires under the APRM mounting bracket. To mount the FWD-BRK-REV switch in the KBPC first remove the rubber plug in the FWD-BRK-REV position by unscrewing the retainer nut on the inside cover. Install the FWD-BRK-REV switch assembly into the front cover making sure the key in the hole lines up with the keyway in the switch bushing. Be sure the hex nut supplied is installed at the base of the switch bushing before inserting switch into the KBPC cover. Install the rubber switch boot with integral hex nut over switch lever. Switch should be in the stop position to facilitate installation. Also, the switch bushing threads should protrude no more than . 25" (6. 4mm) or no less than . 10" (2. 6mm) through the front cover for proper installation. Tighten the switch boot so that the bottom seals against the cover label. 1 ­ APRM® MOUNTED IN THE KBPC-240D 3 5. It is possible to operate the control with a remote FWD-BRK-REV switch or with a remote relay. Carefully remove the three switch wires: S1, S2, S3 from the APRM®. [. . . ] 5 ­ INTERNAL WIRING DIAGRAM To avoid erratic operation do not bundle AC line and motor wires with reversing, potentiometer, voltage following, enable, inhibit or other signal wiring. Use shielded cables on all signal wiring over 12" (30 cm) ­ Do not ground shield. Note: Reversing switch can be remotely mounted. 6 FIG. 7 ­ MECHANICAL SPECIFICATIONS INCHES [mm] 7 V ­ LIMITED WARRANTY For a period of 18 months from date of original purchase, KB will repair or replace without charge devices which our examination proves to be defective in material or workmanship.
