Chapter 1 Introduction The Allen-Bradley Bulletin 1608P HC-DySC Dynamic Sag Corrector is engineered to provide years of trouble-free voltage sag (dip) protection. The patented DySC technology does not use batteries, requires only routine maintenance, includes three-stage transient voltage surge suppression, and has unparalleled energy efficiency. Most electronic devices found in industry today are susceptible to power disturbances.
Chapter 1 ATTENTION: - To reduce the risk of fire or electric shock, install this HC-DySC in a temperature and humidity controlled, indoor environment, free of conductive contaminants. • Avoid installing the HC-DySC directly near heat-emitting equipment such as ovens, heaters, or furnaces. • Ambient temperature must not exceed 40°C (104°F). • Do not operate near water or excessive humidity (95% max).
Chapter 2 Installation Installation Check List Inspecting and Unpacking Before proceeding, please take a few minutes to review the necessary steps to install your HC-DySC. • All packing materials and restraints have been removed. • The HC-DySC is placed in its installed location. • All conduits and cables are properly routed to the HC-DySC. • All power cables are properly terminated. • A ground conductor is properly installed and terminated.
Chapter 2 Installation Floor Mounting The HC-DySC is to be secured to the floor using fasteners and fittings appropriate for the type of floor. Holes are provided in the base channels; see Figure 1 for mounting dimensions. Note: Top or bottom cable entry is allowed. See Figure 1 and Figure 2 on page 9. Figure 1 - Bottom View Floor Mount Dimensions Clearance HC-DySC doors hinge on both right and left. See Figure 10 on page 20 for dimensions including door swing.
Installation Accessing Terminations Chapter 2 For top entry remove the top gland plate, shown in Figure 2, to access input and output terminals. This plate may be removed for drilling or punching holes for conduit. Alternate bottom entry should utilize the bottom gland plate shown in Figure 1. Access to the communications port is above the front doors, as shown in Figure 6 on page 13. A separate conduit knock-out is provided for top entry of communications conductors, as shown in Figure 2.
Chapter 2 Installation 3-Wire vs. 4-Wire Configurations HC-DySC models are available for use with either 3-wire (L1, L2, L3) or 4-wire (L1, L2, L3, N) sources. The input N conductor must be connected to 4-wire models for proper operation. Do not connect a N conductor to 3-wire models. 3- Wire Models Bulletin 1608P part numbers containing V3 are configured for 3-wire source (L1, L2, L3) and 3-wire loads (X1, X2, X3). Do not connect a N conductor to 3-wire models.
Installation 4- Wire Models Chapter 2 Bulletin 1608P part numbers containing V4 are configured for 4-wire source (L1, L2, L3, N) and either 3-wire or 4-wire loads. The source N conductor must be connected for proper operation of these models. Connect both input and output N conductors to the bus bar labeled NEUTRAL (See Figure 5). Figure 4 shows the 4-wire HC-DySC system wiring schematically, including the internal Bypass Switch. Figure 4 - HC-DySC 4-Wire Configuration.
Chapter 2 Installation Electrical Terminations and Ratings Input terminals (top lugs on CBA) are marked L1, L2, and L3 for the source connections. Output terminal blocks are marked X1, X2, and X3 for the load connections (See Figure 5). In 4-wire models only, connect both input and output N conductors to the NEUTRAL bus bar. Do not connect to the NEUTRAL bus bar in 3-wire models. Replace all shields and covers when wiring is completed. The doors must be closed and latched securely.
Chapter 3 Communications Both dry contacts (relays) that indicate status and a Serial Communications Port (RS-232) are available for monitoring the HC-DySC. Dry Contacts Three relay contacts indicate HC-DySC status. The contacts are form A and close upon occurrence of the named event: (a) any SAG EVENT, when rms input voltage drops below 88.5% of rated value; (b) OUTPUT OK, when output voltage remains between 87% and 110%; and (c) a system ALARM event. The relay contact ratings are 24V at 1A.
Chapter 3 Communications Serial Communications Port The HC-DySC serial port is a DE-9 female connector. The pin-out follows standard RS-232 protocol: pin 2 is RxD, pin 3 is TxD and pin 5 is common (return). All other pins are unused. Contacts are galvanically isolated from the system power and grounds. • Protection: The RS-232 port is ESD-protected to 15kV. • Protocol: 57.6k bps, 8 data bits, one stop bit, no parity, flow control off • Data packets are SLIP encoded (with 2 byte length field).
Chapter 4 Applying Power and Operation Applying Power • Before applying power to the HC-DySC, make certain there are no metal filings or any conductive debris in or on any components inside the cabinet. • Verify HC-DySC voltage rating matches ac source voltage. • Ensure all input/output wiring including grounding has been completed and properly tightened. • Verify CBA circuit breaker is in the ON position before replacing covers. Replace all covers. Close and lock cabinet doors.
Chapter 4 Applying Power and Operation HC-DySC System Operation SHOCK HAZARD: Dangerous voltages are present within the HC-DySC System. The unit should never be operated with the enclosure door open except by qualified and authorized personnel who are trained and familiar with the operation of the unit and the location of components and voltages. Failure to comply with this warning could result in injury or death.
Applying Power and Operation Bypass Switch Modes Chapter 4 The bypass switch has three modes of operation and is configured as shown in Figure 9. Figure 9 - Bypass Switch and Mode Operations. • NORMAL Mode – Input and output contacts are closed. Power flows from the utility source through the DYSC electronics to the load. • TEST Mode – Bypass contacts and input contacts are closed. Power flows directly from the utility to the load through the bypass contacts. DYSC outputs are not connected to the load.
Chapter 4 Applying Power and Operation Operating and Alarm Modes Under some conditions the HC-DySC will trip the internal circuit breaker CBI to prevent damage to the HC-DySC or to protect loads from severe voltage unbalance. Those conditions are the last four listed in the table below. ATTENTION: reclosing of CBI will be inhibited for one (1) minute after CBI has opened for any reason. Attempts to close CBI too early will result in immediate re-tripping.
