TM 5-3895-374-24-2 Type D931 Connect lead terminals 1 a 2 for 115 VAC or terminals 2 & 3 for 230 VAC (See Diagram 3). Type D932 Connect  supply  voltage  leads  to  terminals  1  &  2.    (See Diagram 4 and  check  designation  label  on  controller  for correct voltage.) Type D934 Connect  supply  voltage  leads  to  terminals  1  &  2.    (See Diagram   5   and   check   designation   label   on   controller voltage.) SENSOR (INPUT} CONNECTIONS CAUTION:  Do  not  run  sensor  leads  through  same conduit or wireway with power or load leads. THERMOCOUPLE TYPE J (D931) AND TYPES J & K (D932 & D934) • Thermocouple upscale protection for open thermocouple standard. • Always  use  the  thermocouple  extension  wire  and connector matching the thermocouple calibration. • Thermocouple  lead  wire  and  extention  wire  are color  coded.    The  negative  (-)  lead  is  red.    The positive (+) lead is white for Type J and yellow for Type K. • Always use .25 Faston female terminals for sensor input terminal connections. • To compute total thermocouple error in degrees F, select   wire   gauge   and   thermocouple   calibration and   multiple   total   length   of   leadwire   by   value shown  in  table  below.    Divide  by  100  to  compute total setting and indicating error in °F.

Connect sensor (input) leads as follows: Diagram 6 LOAD CONNECTIONS WARNING:     Power     must     not     be     applied     direct between  common  and  heat  (N.O.)  or  common  and cool   (N.C.).      Such   connections   place   the   power directly across the relay contacts and will permanently  damage  the  controller.    The  heat    and cool terminals must be connected to he appropriate loads before being connected to the load power line. NOTE:   Relay(s)   are   energized   below   set   point(s). Pilot light 1 is “on” below set point 1, and pilot light 2  is  'on'  above  set  point  2.    For  standard  units, connect load lines per Diagram 3 (D931), Diagram 4 (D932) or Diagram 5 (D934).  For units with options, make wiring connections as shown in Diagrams 7, 8, and 9. CAUTION:  Using  Non-isolated  4-20  mA  with  Non- isolated load can result in shock hazard. NOTE: Maximum load impedance 750 OHM's. Diagram 8 4-20 mA Option (page 3-716)
