NOTE
The operational test for the lower temperature limit trip is not required on relays with
output options L and M. (The lower trip on these relays is given in Step 3, page 5-1.)
OPERATIONAL TEST OF LOWER TEMPERATURE LIMIT TRIP
Step 1. Connect the relay as shown in Figure 5-1.
Step 2. Set the resistor decade box for 0.0 ohms.
Step 3. Set LOWER TEMP LIMIT °C control to 60.
Step 4. Set UPPER TEMP LIMIT °C control to 190.
Step 5. With relay connecting plug(s) in place, apply appropriate operating power to relay.
Step 6. Observe states of test setup indicators as listed in the following chart.
