Accessories The accessories for these single phase input DC controls are unique and primarily designed to be used with these controls alone. The following is a review of each accessory and where they might be used. BC143 External Heat Sink Used on BC140, BC140-FBR, BC141, and BC142 to achieve maximum output ratings. Bolts to chassis mount or NEMA enclosed control. BC144 Forward Reverse Switch Mounts in BC140 making it into BC140-FBR. Allows forward and reverse direction selection along with dynamic braking on STOP. The toggle switch has detents to help prevent plug reversal. Used for up to 2 HP 180 volt motors. BC145 Signal Isolator Board BC145 mounts as a stand alone or it can be mounted in the cover of BC154 (no F-B-R switch installed). Allows 0-25, 0-120 or 0-550 VDC voltage or 1-5, 4-20 or 10-50 ma current input to the control with a 0-10 VDC output powered from 120 or 230 VAC. It provides an isolated interface between non-isolated signals and Baldor speed controls. BC146 Current Sensing Relay and Overload Protector BC146 is an electronic DC current sensing relay and overload protector for use with motors 1/8-3 HP. Larger motors may be monitored by use of an external shunt. BC146 contains 5 preset current trip points which can be further adjusted with a trim pot. The unit also has provisions for trip time delay. An LED indicates when the preset current trip point has been reached. External contacts are provided which may be connected to sound an alarm or shut the system down in case of an overload. BC147 Barrier Terminal Board BC147 is designed for BC141 or BC142 controls. It provides a terminal strip for control connection instead of the standard push-on terminals. 9
BC148 Replacement Potentiometer Kit BC148 is a standard 5K ohm pot with an insulating washer. It is a replacement for those supplied in or with all small SCR controls. It may also be used with the H series controls as an analog input. BC149 Knob and Dial Kit BC149 is a plastic knob and 0-100% dial that may be used with a remotely mounted potentiometer. BC151 Electronic Speed Potentiometer BC151 is used instead of the control s 5K ohm potentiometer. It is ideally suited for use with SCR controls because its power source is the control s DC field power supply. It is generally used with a set of momentary push button switches (customer supplied). One switch is used to increase speed (UP) and the other to decrease speed (DOWN). The unit contains a meter output that can be used to operate a digital or analog meter. The meter scale can be calibrated to desirable units with built-in meter scale trimpot. Min. and Max. trimpots are used to set the range of motor output speeds. A trimpot allows setting of the rate of speed change. BC151 will be difficult to use as a replacement for a 5K ohm pot on an inverter or vector control because of its need for DC input power and also that its output is not isolated and requires use of a signal isolator board. BC152 Barrier Terminal Board with Signal Isolator BC152 combines the BC145 Signal Isolator and BC147 Barrier Terminal Board into a cost effective board for BC141 and BC142. BC156 Forward-Brake Reverse Switch BC156 is for BC154 (a replacement for BCWD140). Allows forward and reverse direction selection along with dynamic braking. Not used on BC160 (cannot handle 3HP current). 10
BC157 Run-Jog Switch BC157 is for BC154 or BC160 (a replacement for BCWD140). Allows a JOG function along with continuous RUN. BC158 Auto/Manual Kit BC158 is a toggle switch for BC154 or BC160, which is used in conjunction with an internally mounted BC145, allowing manual use from the switches or automatic use from the input signal to the BC145. BC159 AC Line Switch BC159 is used to break both lines of the AC input on BC154 or BCWD140. It may be used with wound field motors so the fields will not be continuously energized when AC line power is present. Our BCWD140, either the START-RUN or RUN-JOG switches must be removed to allow mounting space. Not used with BC160 because of higher line current. BC211 Quadrant Accel/Decel Board BC211 is used with BC200, BC201, BC202 or BC203 to allow for independent and separate adjustment of forward accel and decel and reverse accel and decel. Without BC211, the pot for forward accel also controls reverse decel, and the reverse accel pot also controls forward decel. BC211 provides 4 adjustment pots, one for each setting. It connects to BC200 or BC201 with a ribbon cable and mounts under the main control board in a slot provided in the extrusion. BC212 Bipolar Signal Isolator The BC212 is used with BC200, BC201, BC202 or BC203 and mounts below the main control board in a slot in the extrusion. A built-in power supply is now included. BC212 provides complete electrical isolation between input voltage signals which are derived from PLC s transducers and digital/analog converters. There are two input ranges: ± 25 VDC and ± 250 VDC which are jumper selectable. The input/output ratio can be scaled via the included zero and Max. trimpots. 11
