Trane TR200 Series User Manual

6-16 Terminal 53 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10.000 s] Enter the time constant. This is a first-order digital low pass filter time
constant for suppressing electrical noise in terminal 53. A high time con-
stant value improves dampening but also increases the time delay
through the filter.
This parameter cannot be adjusted while the motor is running.
6-17 Terminal 53 Live Zero
Option: Function:
This parameter makes it possible to disable the Live Zero monitoring.
E.g. to be used if the analog outputs are used as part of a de-central I/O
system (e.g. when not as part of any frequency converter related control
functions, but feeding a Building Management system with data).
[0] Disabled
[1] * Enabled
6-2* Analog Input 2
Parameters for configuring the scaling and limits for analog input 2 (terminal 54).
6-20 Terminal 54 Low Voltage
Range: Function:
0.07 V* [0.00 - par. 6-21 V] Enter the low voltage value. This analog input scaling value should cor-
respond to the low reference/feedback value, set in par.6-24
Terminal 54
Low Ref./Feedb. Value.
6-21 Terminal 54 High Voltage
Range: Function:
10.00 V* [par. 6-20 - 10.00 V] Enter the high voltage value. This analog input scaling value should cor-
respond to the high reference/feedback value set in par.6-25
Terminal 54
High Ref./Feedb. Value.
6-22 Terminal 54 Low Current
Range: Function:
4.00
mA*
[0.00 - par. 6-23 mA] Enter the low current value. This reference signal should correspond to
the low reference/feedback value, set in par.6-24
Terminal 54 Low Ref./
Feedb. Value. The value must be set at >2 mA in order to activate the Live
Zero Time-out Function in par.6-01
Live Zero Timeout Function.
6-23 Terminal 54 High Current
Range: Function:
20.00
mA*
[par. 6-22 - 20.00 mA] Enter the high current value corresponding to the high reference/feed-
back value set in par.6-25
Terminal 54 High Ref./Feedb. Value.
6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
0.000 N/
A*
[-999999.999 - 999999.999
N/A]
Enter the analog input scaling value that corresponds to the low voltage/
low current value set in par.6-20
Terminal 54 Low Voltage and par.
6-22
Terminal 54 Low Current.
