Rockwell Automation 900-TC32 Digital Temperature Controllers, Series B - Manual (Page 82)

Publication 900-UM007D-EN-E - January 2011
3-12 Configuration & Basic Operation
Configuring the Input Type The Bulletin 900-TC8, 900-TC16, and 900-TC32 controller support three
input/sensor types: (1) platinum resistance thermometer (RTD), (2)
thermocouple, and (3) non-contact temperature sensor. The Bulletin 900-TC8
and 900-TC16 controller support a fourth input/sensor type, analog inputs.
Program/configure the Input Type matched to your sensor using the Input
Type parameter (See Table 3.C). The Bulletin 900-TC8, 900-TC16, and
900-TC32 general controller specifications support two general types of
Global Temperature (GT) inputs: (1) platinum resistance thermometer input
and (2) thermocouple Input Types (refer to Table 3.C). The Bulletin 900-TC8
and 900-TC16 controller support a third a third GT input, analog inputs (refer
to Table 3.D). Check the cat. no. of your Bulletin 900 components at purchase
to ensure it matches your input requirements (refer to Tables 1.B and 1.D).
Input Type
Example Operation Procedure: Setting the Input Type to Thermocouple
Type K (–20.0…500.0
°C) (See Table 3.C, — List of Global Temperature (GT)
Input Types)
1. Press the
O
key for at least 3 seconds to move from the Operation
function group to the Initial Setting function group.
Figure 3.10 — Operation Function Group
Figure 3.11 — Initial Setting Function Group
2. Press the
U key to configure the Set Value for the type of sensor you
are using. Entering the Set Value will configure the controller for the
applicable Input Type and range. Example: When you use K
thermocouple (–20.0…+500.0
°C), enter 6 as the Set Value (refer to
Table 3.C).
Note: The selected Set Value is loaded into controller memory if you do not
operate the keys on the front panel for 2 seconds after changing the
parameter, or by pressing the
O
or
M keys. This applies to changing
all values and/or parameters.
