2. SCF REMOTE KEYPAD TEMPLATE NOTE: Verify dimensions on printed page before using as a template. Hold this page against the panel where the remote keypad is to be mounted, and use a center punch to mark the location of the three holes. The dotted line is the outline of the remote keypad. 4. WIRING CONNECTIONS WARNING! Improper wiring may result in damage to the Remote Keypad. Keep the remote keypad cable away from power wiring. The Belden and Carol cables specified consist of two twisted pairs. Make sure one twisted pair is used for power and the other is used for serial communications. Do not mix connections between twisted pairs Note 1: The supplied cable can be used for distances up to 8 feet in low- noise environments. For distances up to 100 feet, or in high-noise environments, use Belden 9842, Carol C4842, or equivalent (24 gauge minimum) wire only. SCF SERIES REMOTE KEYPAD INSTRUCTIONS (Manual Number: KF01G) The SCF Series Remote Keypad option (844-200) allows the SCF Series drive to be programmed and controlled from up to one hundred feet away. When properly mounted, the remote keypad is rated NEMA 4X. In addition to the functions available on the front of the SCF drive, the remote keypad has Start/Stop and Forward/Reverse functions. Note: The Remote Keypad option will only work with SCF drives that have parameter version “309” or “312”. It will not work with SCF drives that have the High Frequency or PI Setpoint Control options. The parameter version appears momentarily on the drive display when it is powered up, and also appears on a small label on the drive’s heatsink. WARNING! If OEM mode is selected (using Parameter 48), and if the OEM Default setting for Parameter 14 and/or 15 is “01”, the remote keypad will be disabled, and the STOP key WILL NOT work. Refer to the SCF Installation and Operation Manual for information on OEM Default settings. 1. PARTS LIST The SCF Remote Keypad kit includes the following parts: (1) Remote Keypad (1) Gasket (2) Self-tapping Mounting Screws (1) Instruction Sheet (1) Eight foot cable Note: The supplied cable can only be used for distances up to 8 feet in low- noise environments. For distances up to 100 feet, or in high-noise environments, use Belden 9842, Carol C4842, or equivalent (24 gauge minimum) wire only.

MOUNTING THE REMOTE KEYPAD The diagram below illustrates how to mount the remote keypad to a panel. Use the template in Section 2 to mark the location of the mounting holes on the panel. Note 2: TB-11 can supply up to 50 mA of power, and the remote keypad requires 40 mA. To drive auxiliary relays using the open-collector outputs, an external power supply is required. • 630 Douglas Street • Uxbridge, MA 01569 • USA • Sales (800) 217-9100 • Service (508) 278-9100 • www.lenze-actech.com

This guide is intended as an aid to configure the SCF drive. NOTE: Before installing and operating the SCF drive, please read and become familiar with the SCF Series installation and operation manual. SCF TERMINAL STRIP QR-SCF-OEOD-e2 PI CONTROL WIRING EXAMPLE Shown below is a wiring diagram for a typical PI control scheme with a 2-wire start/stop and 4-20 mA feedback. The PI setpoint is adjusted using the  and  butons on the front of the drive. - Set Parameter 10 (TB-13A) to Keypad Setpoint (12). - Set Parameter 61 (PI MODE) to Normal 4-20 mA (02) or Reverse 4-20 mA (04) depending on the type of system to be controlled. - Set the other PI parameters as necessary (refer to the SCF manual).

EI EXTERNAL CURRENT: The drive speed is controlled by a 4-20 mA signal between TB-25 and TB-2. EU EXTERNAL VOLTAGE: The drive speed is controlled by a 0-10 VDC signal between TB-5 and TB-2. JG JOG: The drive is in Jog mode and the speed is set by preset speed #2 (Parameter 32). OP MOP: Contacts wired to TB-13B and 13C are used to increase and decrease the drive speed. Pr1 - Pr7 PRESET SPEEDS #1-7: The drive speed is set by the selected Preset Speed (Param- eters 31-37). Status Indication br DC BRAKING: The DC braking circuit is activated. CL CURRENT LIMIT: The output current has exceeded the CURRENT LIMIT setting (Parameter 25) and the drive is reducing the output frequency to reduce the output current. If the drive remains in CURRENT LIMIT for too long, it can trip into a CUR- RENT OVERLOAD fault (PF). Er ERROR: Invalid data has been entered. GE “GE” will be displayed if an attempt is made to change the OEM default settings when the drive is operating in the OEM mode (see Parameter 48). LC FAULT LOCKOUT: Failed three restart attempts. Requires a manual reset. SE SERIAL: The optional remote keypad is active as the user interface instead of the but- tons on the front of the drive. SP START PENDING: This is displayed during the 15 second interval between restart attempts. Diagnostic Codes AF HIGH TEMPERATURE FAULT: Ambient temperature is too high. CF CONTROL FAULT: A blank EPM, or EPM with corrupted data has been installed. Perform a factory reset (Parameter 48). cF INCOMPATIBILITY FAULT: An EPM with a different parameter version has been installed. dF DYNAMIC BRAKING FAULT: The drive has sensed the dynamic braking resistors are overheating. EF EXTERNAL FAULT: TB-13A and/or TB13C is set as an external fault input and TB-13A and/or TB-13C is open with respect to TB-2. GF DATA FAULT: User data and OEM defaults in the EPM are corrupted. HF HIGH DC BUS VOLTAGE FAULT: Line voltage is too high; Deceleration rate is too fast; Overhauling load. Fast deceleration and overhauling loads may require dynamic braking. JF SERIAL FAULT: The watchdog timer has timed out, indicating that the serial link has been lost. LF LOW DC BUS VOLTAGE FAULT: Line voltage is too low. OF OUTPUT TRANSISTOR FAULT: Phase to phase or phase to ground short circuit on the output; Failed output transistor; Boost settings are too high; Acceleration rate is too fast. PF CURRENT OVERLOAD FAULT: VFD is undersized for the application; Mechanical problem with the driven equipment. SF SINGLE-PHASE FAULT: Single-phase input power has been applied to a three-phase drive. UF START FAULT: Start command was present when the drive was powered up. Must wait 2 seconds after power-up to apply Start command if START METHOD is set to NORMAL. F1 EPM FAULT: The EPM is missing or damaged. F2 - F9, Fo INTERNAL FAULTS: The control board has sensed a problem. Consult factory AC Technology Corporation 630 Douglas St, Uxbridge, MA 01569 800-217-9100, FAX: 508-278-7873 www.actechdrives.com
