Step 7. Set LOWER TEMP LIMIT °C control to the lower temperature limit to be tested.
Step 8. Gradually increase the decade box resistance until a lower temperature limit trip indication (DS2) is
observed. The chart below presents the trip indications for all relay output options.

Step 9. Read resistance from decade box. Refer to Figure 5-2, Temperature/ Resistance, to verify the
temperature at which the trip occurred.
Step 10. Adjust LOWER TEMP LIMIT °C as necessary and repeat steps 8 and 9 until lower temperature limit
trip occurs at desired temperature.
Step 11. Determine the resistance that corresponds to a level 10°C below the lower limit setting from Figure
5-2, then adjust resistor decade box for resistance value obtained. Observe relay resets by the
indication in chart below.

TRIP POINT SELECTION (EXCEPT OUTPUT OPTIONS L and M)
This procedure provides a method for selecting the upper and lower temperature limit trip points. The lower
trip point is selected first. If only the upper trip selection is desired, perform steps 1, 3, 9, 10 and 11.
Step 1. Connect the relay as shown in Figure 5-1.
Step 2. Set the LOWER TEMP LIMIT °C control to at least 10°C above the intended lower temperature limit
trip point.
Step 3. Set UPPER TEMP LIMIT °C control to 190.
