Outline dimension drawing(s) that identify the physical characteristics of the controller and contain installation information. Instruction Bulletin VD0C3S30, which describes the operation and characteristics of the ATS6 controller when used as a component of the Class 8638 or 8639 Enclosed Controller. DANGER HAZARDOUS VOLTAGE Disconnect all power before working on this equipment. Failure to observe this instruction will result in death or serious injury. Read, understand and follow all precautions contained in bulletin VD0C3S30. In addition, the following precautions unique to the Enclosed ATS6 Controller must be followed: The Enclosed ATS6 Controller can be installed in a Pollution Degree 3 environment, as defined in NEMA ICS-A and IEC 66-. When attaching wall mounted and free standing controllers, use fasteners rated for the weight of the apparatus, the expected shock and vibration of the installation, and the expected environment. During installation and operation, maintain the ventilation clearances specified on the outline dimension drawing(s). EXCEPTIONS TO BULLETIN VD0C3S30 When referencing Instruction Bulletin VD0C3S30 for Class 8638 or 8639 Enclosed ATS6 Controllers, note the following: The recommended components listed in Table 8 on pages 3 and 3 apply to Open ATS6 Controllers only. Refer to Tables 3-6 in this document for actual components used in Class 8638 and 8639 Enclosed ATS6 Controllers. The recommended overcurrent protection devices (OCPDs) listed in Table 9 of Appendix A apply to Open ATS6 Controllers. Refer to Tables 3-6 in this document for the OCPDs to be used with Class 8638 and 8639 Enclosed ATS6 Controllers. The dimensions listed on pages 0- (Figures 6-0) apply to Open ATS6 Controllers only. Refer to the specific documentation for the enclosed controller class you have (8638 or 8639). The Control Connections section on page may not apply to Class 8638 or 8639 Enclosed ATS6 Controllers, since the relay contacts shown may be incorporated into the control logic of the Enclosed product and may not be available for user connection.

9 Bulletin No May 997 Enclosed ATS6 Controller Supplemental Instruction Bulletin s FACTORY PRESETS The Enclosed ATS6 Controller, used as a component of Class 8638 or 8639, has a configuration switch that has been preset at the factory for either normal or long starting times. The factory presets are shown below. Parameter Switch Position Type N Standard Duty NOTE: For FLA factory presets, refer to Tables 3 and 6 in this document. Type L Heavy Duty Acceleration Ramp Acc 0 seconds seconds Current Limit Ilt 300% 30% Overload Protection thp Class 0 Class 0 To change the factory presets, the keypad must be removed from the enclosure door. For information on adjusting the factory presets, refer to Chapter 3 of Instruction Bulletin VD0C3S30. When replacing the keypad in the remote mounting, do not exceed 3 lb-in torque on the holding screws. Class 8638 and 8639 control logic may include one or more pneumatic time delay relays. The factory settings are as follows: Shunt trip power circuit: TR is factory set for seconds. Do not adjust. This time delay prevents the controller from fault tripping on startup. Isolation Contactor Power Circuit: The isolation contactor is controlled by the R relay and automatically adapts to the deceleration requirements, which may be changed at any time. The configuration of the R relay has been changed from the Fault configuration, which is used for the Shunt Trip and Reversing Power Circuits. Reversing power circuit: RFR and RRR - set for minimum setting (0 seconds). For freewheel stopping, the factory setting is adequate. For controlled deceleration, set slightly longer than the deceleration ramp time (DEC parameter setting). When using InTele braking, set the time delay relay to the maximum adjustment. After the stopping time is determined, the delay can be reduced to more closely match the braking application time. 997 Square D Company All Rights Reserved 9
