7 / 32 page  77 3.0 Wiring The COnTrOller WIRING CONNECTIONS All wiring connections are made to the rear screw terminals. When wiring the controller, use the numbers on the label and those embossed on the back of the case, to identify the position number with the proper function. All conductors should meet voltage and current ratings for each terminal. Also, cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power (AC or DC) supplied to the controller be protected by a fuse or circuit breaker. Strip the wire, leaving approximately 1/4" (6 mm) bare wire exposed (stranded wires should be tinned with solder). Insert the wire under the clamping washer and tighten the screw until the wire is clamped tightly. 1 L 50/60 Hz 5VA AC 100-240V N 2 13 14 User1 8 7 + - 15 9 3 User 2 410 16 AL1 AL2 OP 2 / AL 3 + - 11 17 5 12 18 6 RTD OP 1RS-485 D D - + + IN Tc + -- + - - + AC 100~240V 50/60 Hz 5VA 1 ~ 13 2 14 3 15 4 16 5 17 618 7 19 8 20 921 10 22 11 23 12 24 IN Tc NO D- L N NO D+ RS-485 NO NO NC AL 1 AL 2 OP 1 User 2 User 1 OP 2/ AL 3 + ++ + + + - - - - - - 1/16 DIN 1/8 or 1/4 DIN CONTROLLER POWER CONNECTIONS For best results, the power should be relatively “clean” and within the specified limits. Drawing power from heavily loaded circuits or from circuits that also power loads that cycle on and off should be avoided. It is recommended that power supplied to the controller be protected by a fuse or circuit breaker. 2 1 L N AC 100-240V 50/60 Hz 5VA INPUT CONNECTIONS For two wire RTDs, install a copper sense lead of the same gauge and length as the RTD leads. Attach one end of the wire at the probe and the other end to input common terminal. This is the preferred method as it provides complete lead wire compensation. If a sense wire is not used, then use a jumper. A temperature offset error will exist. The error may be compensated by programming a temperature offset. 12 11 10 TC- TC+ 12 11 DC+ VOLTAGE/CURRENT DC- VOLTAGE/CURRENT 12 11 CONTROL AND ALARM OUTPUT CONNECTIONS VAC RTD and Resistance Thermocouple and Millivolt Voltage and Current LOAD AC/DC Power (-) LOAD COMM NO NO AC/DC Power (+) AL 2 AL 1 AC/DC Power LOAD COMM (-) NO (+) AC Power SSR COMM (-) NO (+) POWER UNIT + - AC AC Alarm 1 and 2 * (1/16 DIN Shown) OP1/OP2 Output Control Relay * OP1 Output Control Logic/SSR * USER INPUT CONNECTIONS * User 1 + User 2 + - - * See unit label for terminal identification.
