TABLE 3 – SELECTABLE JUMPER REFERENCE CHART Jumper Location* Description Factory Setting J1 1 Establishes the range of maximum armature current See section III, page 8 J2A, J2B 1 Sets the AC input line voltage (120 or 240 Volts AC) for the main PC Board Set according to model part numbers. See table 1, Page 3 J3 1 Sets the DC output voltage range to motor (90V/180V) Set according to model part numbers. See table 1, Page 3 JR 1 Used to activate the return (RTN) circuit.
Failure to follow the Safety Warning Instructions may result in electric shock, fire or explosion. Do not fuse neutral or grounded conductors. Note: See section V, Fusing, on page 10. A separate AC line switch, or contactor, must be wired as a disconnect switch, so that the contacts open each ungrounded conductor. (See figure 4, below for AC Line and Armature Connection.) Note: Do not bundle AC or motor leads with logic leads or erratic operation may occur.
1. Remote Potentiometer. Connect remote potentiometer wires to terminals P1, P2 and P3, so that the “high” side of the potentiometer connects to P3, the “wiper” to P2 and the “low” side to P1. (See figure 5.) 2. Analog Input. An isolated 0-10VDC analog voltage can also be used to drive the control. Note: If an isolated signal voltage is not available, an optional signal isolator (Camco P/N 99A61455000000) should be used. Connect the isolated input voltage to terminal P2 (positive) and P1 (negative).
B. ”JOG” (Stop) – A maintained contact closure between terminals “JOG” and “RTN” will cause the control to run continuously. This is not a latching function. The drive will run only as long as the contact is closed and stop when it is opened. (See figure 8.) Application Note: The “JOG” can also be used as a normally open (NO) “STOP” command. When the control is started with the momentary “RUN” command, it can be stopped by connecting a momentary contact between the “JOG” and the “RTN” terminals.
TABLE 6 – JUMPER “JW” OPERATION Jumper “JW” Setting Description Circuit RUN S R JW Factory setting JOG “Run” has priority over “Stop.” Control will run even if stop contact is open. Use this setting for “Cycle on Demand” operation. STP Operation RTN * STOP When start contact is made, control will run with stop open. If stop is closed and then reopened, control will stop. START RUN S R JW JOG “Stop” has priority over “Run.” Control will run only when stop contact is closed.
Capable of switching 30 VDC, at 24 mA, with an off-state leakage current of less than 1 mA. (See figure 12.) Warning! Do not ground or short +24V to COM or return on TB1. Do not use +24V for other than open collector sensors. (See figure 12.) Example 2: For optimum operation, contacts used on logic inputs should be rated for low-level logic switching (i.e. gold contacts). (See figure13.
FIGURE 14B – RIGHT ANGLE UNIT FIGURE 14C – PARALLEL UNIT Keyway Keyway A standard right angle unit with the CAM & Limit Switch mounted on the housing has a correct keyway position directly opposite of the CAM Lobe. CAM & Limit Switch may also be mounted on the reducer. The “Cycle on Demand” function is required for most indexing table applications. The control can be easily set for this operation as follows: 1. Jumper “JW” must be in the “R” position (factory setting) see table 6, on page 12. 2.

WARNING! Do not adjust trimpots with main power on if possible. If adjustments are made with power on, insulated adjustment tools must be used and safety glasses must be worn. High voltage exists in this control. Electrocution and/or fire can result if caution is not exercised. Safety Warning on page 2 must be read and understood before proceeding. Failure to follow the Safety Warning Instructions may result in electric shock, fire or explosion. ! A.
C. Overload Indicator (OL) – When the motor is loaded to the current limit setpoint (CL setpoint is established by the setting of jumper J1 and the CL trimpot) this lamp will glow RED. If the OL indicator remains lighted during control operation, a fault condition may exist. Possible causes for this condition are as follows: 1. Motor is overloaded - check motor amps with DC ammeter in series with armature. 2. Motor may be defective - check motor for shorts or grounds. 3.
XII – TROUBLESHOOTING GUIDE MOTOR WILL NOT RUN: 1. Check control operation by placing RUN - JOG/STOP in RUN position. 2. Make sure disconnect fuses or circuit breaker in AC line are okay. 3. Check fuse on PC board, and if open, replace. 4. Check logic. See Start-up Procedures and Application Section. 5. Be sure speed pot is not set at zero. 6. Unit is in current limit – See if “OL” indicator is lighted. Check position of jumper J1. (See table 4, p. 8) and CL trimpot setting. 7.
