EA200 / EA400 Sensor Connections
Note: Sensors required should be on-hand before attempting installation. Refer to
“Accessories” on page 44 for information regarding available sensors and their
recommended applications.
Note: The EA200 / EA400 can be used with earlier-version Winland temperature
sensors ( Model Numbers TA-S-D, TA-S-H, TA-S-L). However, for new
installations it is recommended that the current Winland temperature sensors
be used. See “Accessories” on page 44 for descriptions and part numbers of
current Winland sensors.
1. Install and wire all required external (remote location) sensors between the sensor
and the EA200 / EA400 mounting location. Use a wiring scheme that identifies
sensor wiring polarity. (The TEMP-H-S, TEMP-L-S, TEMP-L-W, and TEMP-H-W
thermistor temperature sensors are not polarity-sensitive.)
2. Determine the sensor-to-Zone allotment to be used with the EA200 or EA400 being
installed. The table below shows the lists the Zones for the EA200 and EA400.
3. Using the Terminal Block Adapter included with the sensor, connect the sensor
wires to the appropriate SENSOR IN (+) and (–) connector on EA200 / EA400 circuit
board header connector as shown in Figure 7. Where applicable, observe proper
polarity.
4. Repeat the above step for each sensor.
