Figure 1. Panel Cut Out From the front of the panel, slide the housing through the cut out. The housing gasket should be against the housing flange before installing. From the rear of the panel slide the mounting collar over the housing. Hold the housing with one hand and using the other hand, push the collar evenly against the panel until the spring loops are slightly compressed. The ratchets will hold the mounting collar and housing in place. PANEL GASKET 10mm (0.25") MAX.

Instrument installed in Panel 949-1134 Page 4 December, 1999 WIRING Sensor leads should not run in the same conduit as power leads. Use only the type of sensor specified for your instrument range. Thermo- couple input instruments are equipped with automatic sensor break protection. Upon sensor break, the control output to a heating load will turn off. For 3 wire RTD connect the wires to terminals 1, 2, & 3 as shown. If a 2 wire RTD is being used, connect it across terminals 1 & 2 and either: (1) Run a wire from terminal 3 to the side of the probe that connects to terminal 2 to parially compensate for lead resistance; or (2) Jumper terminal 3 to terminal 2 (will not compensate for lead resistance). RTD input models include sensor open and short protection. WIRING DIAGRAMS INPUTS Relay** Solid State 5VDC Output Current N.O.

Option 218 Wiring ALARM OUTPUT SETUP This output type can be set up to be used in one of four different applications: reverse acting On-Off for heating, direct acting On-Off for cooling, High Alarm, or Low Alarm. The functions are described in the chart (next page). On controls with Auxillary Alarm, the alarm point can be adjusted ±20% from the main setpoint with the adjustment on the lower left hand corner of the control. The selection of action and reset functions are set by switches which are located on the component side of the circuit board on the right side of the control (see Figure 1 below). Figure 5. Action and On/Off Alarm Switches. (Switch positions illustrate High Alarm operation.) For newer models select the action by setting switch 1 on and switch 2 off (direct acting) or switch 1 off and switch 2 on (reverse acting). Switch 3 determines whether the output will reset after the temperature has moved to the other side of the set point. If switch 3 is on then the output will automatically reset. If switch 3 is off then the RESET button on the front of the control must be pushed before the output will reset. 949-1134 Page 6 December, 1999 OUTPUT FUNCTION CHART The following chart describes the function and action of the available outputs. Action of the auxillary alarm is the same as for the alarm outputs. Instructions for setup of the alarm outputs is described on the previous page. ORDER CONTROL PROP.

When lit, the status LED indicates that the output is energized. For normal heating control the temperature will start out below the set point, the status LED and the output will be 100% “On”. As the process input approaches the set point the LED and the output will change as described in the chart opposite. The deviation indicator will show the position of the input. When the deviation indicator green LED is lit, the temperature is whithin ±1.5% of set point. If one of the red deviation DEVIATION INDICATOR LEDs indicator LEDs are lit, the tem- perature is above or below the RED LED GREEN LED RED LED setpoint by more than 1.5%.

On Time Proportioning and Proportional models if the input stabilizes below the set point then the Offset Correct adjustment should be turned clockwise in small increments until the deviation indicator green LED is lit. If the input stabilizes above the set point then adjust the Offset Correct counterclock- wise. 949-1134 Page 8 December, 1999 SPECIFICATIONS Inputs: Thermocouple, RTD, Thermistor Input Impedance: • Thermocouple = 3 megohms minimum RTD current = 500 µA maximum Thermistor current = 250 µA maximum Maximum Thermocouple Resistance: 200 ohms with rated accuracy.

December, 1999 Page 9 949-1134 OPTIONS One or more of the following options may be found on your control. 210 Set Point knob lock. This option is not available with the Auxillary Alarm. This allows the Set Point knob to be secured in a fixed position to discourage tampering. Loosen the screw in the center of the locking mechanism, adjust the set point knob to the desired setting, and re- tighten the screw. Overtightening will damage the control. 215 Alarm Power Interrupt. This option allows the alarm to be reset on power up if no true alarm condition exists. Operation is automatic. No adjustments are required. 218 Process Signal Output. This is a non-Isolated 0 to 1 VDC, 0 to 1 mADC output signal that tracks the input. This output is not linearized. Input impedance of the recorder (or other receiving device) must be 1000 ohms. This output is available from the Auxillary Input/Output terminals 11 (negative) and 12 (positive). 2102 FM Approved Setpoint Knob Lock. This option is not available with Auxillary Alarm. Similar to option 210 above, option 2102 makes the control an FM Approved limit control and has a set point knob that locks. The knob lock is constructed using special non-standard hex key that can only be tightened or loosened with a special hex key that is shipped with the instrument. The instrument is configured as a high limit at the factory. Spare hex keys can be purchased by our part number 961-0104. 2502 Control powered from 12 to 24 V AC/DC supply. Power to the control is low voltage. In place of line voltage wire the low voltage supply to terminals 13 and 14. The power input can be AC or DC. The input is not polarity sensitive. Note that the output ratings are not changed. The SSR outputs will not switch loads lower than 60 VAC and /or 100 milliamps. . 949-1134 Page 10 December, 1999 NOTES December, 1999 Page 11 949-1134 DIMENSIONS 949-1134 Page 12 December, 1999 10.2 (0.400) 125 (4.925) 48 (1.880) 114 (4.475) CONTROLS SET 400 300 500 RESET POINT 200 200 600 100 300 48 45 100 700 (1.880) 400 (1.760) 0 0 C J 800 F ALARM OFFSET ADJUST CORRECT 12 (0.450) * 3 (0.125) Panel cutout for all models is 45mm x 45mm (1.775in x 1.775in).
