the FCC rules limits are designed to provide reasonable against harmful interference when the is operated in a commercial This equipment generates uses can radiate radio frequency energy and if not and used in accordance with the manual may cause harmful to radio communications Operation this equipment in a residential area is likely to harmful interference in which case the user be required to correct the interference at his expense AND ACCESSORIES Guidelines TO CONTROLLER WlT xB 5 PLATE IATE INSTALLING THE MPC SSR BE SURE THAT THE CONTROLLER IS FASTENED TO THE ENCLOSURE MPC SSR Output Module 1 Guidelines of electrical shock more than one switch may be required to equipment before servicing power supply from associated controller before installing MPC to prevent electrical shock and equipment not attempt to power the unit ON until is complete MPC SSR is a printed circuit board that fits any of the four option slots on the To install remove power from the and insert the MPC SSR into the option slot on the MSC MPC Wiring diagrams and software assignments provided below installin is fu f after the backplate is fastened to the MPC SSR be sure that the seated to the backplate before reduce risk of fire or electrical shock install in controlled environment relatively free of beginning the installation process for the visually inspect the unit for any defects and to make sure all parts are If any flaws are detected contact your Siebe office or authorized representative information is contained in this For further details regarding software please refer to the appropriate Guide and the MicroSmart Operator User Guide IN THIS PACKAGE MPC SSR module is supplied with One Nl 1122 MPC SSR module circuit board Two 8 pin connectors green N100 410659 connection to outputs Dl D8 COMPONENTS MPC SSR requires direct connection to an MicroSmart MSC MPC Multi purpose REQUIREMENTS MPC SSR module is powered by the on which it is installed for the outputs must be supplied by a 24Vac or dc source This voltage can be by a separate 120 24OVac user stepdown a power rating sufficient for the device being which should Guidelines INSTRUCTIONS AND INFORMATION Outputs eight digital outputs provided at terminals Dl D8 can be used as standard start stop These outputs are rated 0 24Vac or Vdc 24VA 1 amp These electrical outputs are and electrically isolated from one another to Figure 2 below for wiring and setup Hardware assignments for electrical Dl D8 are shown in Table 1 Diaital Outouts for the digital outputs must be supplied by separate 24Vac source This voltage can be by a separate 120 24OVac user step down transformer which should a power rating sufficient for the current of device being controlled For a typical wiring showing connection between the digital and an ac pilot duty relay see Figure 2 Diaital Outouts the outputs are protected from surges circuitry on the controller excessive voltage generated by inductive loads could damage them To prevent this install a purpose diode such as 1 N4004 across load as shown below The cathode side of diode should go to the positive side of the This diode is not required for non inductive For a typical wiring example showing between the digital outputs and a dc duty relay see Figure 3 below SIDE SWITCHING OUTPUT DC TRANSFORMER OUTPUTS ALL WIRE LENGTH MUST BE 200 OR LESS LOAD 1 O AMPS PROTECTION FOR INDUCTIVE ONLY SIDE SWITCHING OUTPUTS VOLTS DC N4004 ALL WIRE LENGTH MUST BE 200 FEET OR LESS THE DIODE MUST BE LOCATED AT THE TERMINALS OF THE LOAD DO NOT USE THE WITH AC LOADS AC
