YP7999A1000 CONTROLINKS™ FUEL AIR RATIO CONTROL PANEL66-2060—01 41 Carefully check field wiring and terminal designations in this document and the associated wiring diagram. They are differentfrom those of the individual components.2 The circuit protection incorporated into this control panel is designed to serve as supplemental protection only. It is the respon-sibility of the end user to provide appropriate protection on the service to this control panel. Refer to the National Electric Codeand UL standard 1077 for more information on this subject. Use 16 AWG MTW wire.3 Low voltage wire to the firing rate actuators must be run in separate conduit. Line voltage wiring to actuators may be obtainedfrom terminals 4, 2 and GND or provided by customer. Run line voltage wires in separate conduit. Refer to the ML7999A prod-uct sheet for details.4 Connect the shield ground of the ML7999A actuator(s) to the earth ground strip provided in the Q7999 universal subbase, onthe low voltage side. Connect the shield at the controller end only. Refer to the ML7999A product sheet for details.5 COM 2 on the S7999D is wired to field terminals for customer use. Customer may wire an existing Modbus-capable RM78xxLburner control and/or Modbus-enabled UDC2500/3200/3500 controls in a daisy-chain fashion to the customer terminals for dis-play on the S7999D. Refer to the S7999D, S7800A or S7810M and UDC control product manuals for further information on wir-ing and S7999D display set-up.6 Installation, operation and maintenance shall conform with National Fire Protection Association standards, national and localcodes and authorities having jurisdiction.7 For detailed device wiring information, refer to the R7999, Q7999A, ML7999A and S7999D1048 product sheets.2153,4 DR1 FGR/4th Channel Actuator DR1 command input2163,4 DR2 FGR/4th Channel Actuator DR2 command input2173,4 CW FGR/4th Channel Actuator potentiometer CW output2183,4 S FGR/4th Channel Actuator potentiometer S output2193,4 CCW FGR/4th Channel Actuator potentiometer CCW outputGND3,4 Ground FGR/4th Channel Actuator ground223 XmA+ Auxiliary 4-20mA+ input from Stack/Water temperature sensor (used for low fire hold)220 XmA- Auxiliary 4-20mA- input from Stack/Water temperature sensor (used for low fire hold)224 CmA+ 4-20mA+ input from Firing Rate control225 CmA- 4-20mA- input from Firing Rate control2315 COM 2 A S7999D COM 2 Modbus A / Data + terminal2325 COM 2 B S7999D COM 2 Modbus B / Data - terminal2285 COM 2 GND S7999D COM 2 Modbus C / Ground terminalTable 1.
