Table 2: analog input
Specifies the analog input signals for the controller. Analog inputs are used to connect sensors like
thermocouples, resistors, voltage/current signals to the controller. You can exactly define signal type (voltage,
resistance, current) as well as signal range, signal conversion and correction, unit etc. The most common signal
types are predefined. Each column of the table defines one process value which are named IN00, IN01 etc. The
maximum number of analog input depends on the hardware.
.
00: input mode
(options END, T/C, LIN, ATMS, RES)
type of the analog input signal. Choose the appropriate kind of signal conversion from the given options:
T/C: Thermocouple input type. Selection of thermocouple and compensation mode see parameter below
LIN: Linear input type for generic use. This mode is used to convert any kind of linear input signal (as defined in
the corresponding parameters) into its process parameter. An example for a typical application is to convert a
4-20mA signal from a pressure transducer into 0 to 100 Pa process parameter
ATMS: Atmosphere signal conversion. Use this selection to convert the typical signal of a circonoxyde probe
into the kiln atmosphere reading. The controller uses the equation of Nerntzsch to convert the probe signal
into % of oxygen. The probe temperature required for oxygen calculation is specified in the corresponding
parameters as well as the kind of gas required for the carbonmonoxyde calculation. Note below on
temperatures below 650°C no oxygen calculation is done (no reliable probe signal)
RES: Resistance temperature sensor conversion. Converts the resistance characteristic of most commonly used
resistance sensors (like Pt100) into temperature reading
01: signal source
(value range AI0.0 to AI1.0)
Specifies a physical input (AI..) of the controller. The process parameter is created from the signal on this
physical input. To create two different process parameters from one physical input make sure that both signal
types and ranges equals
02: average cycles
(value range 1 to 11)
Specifies the low pass signal filter. This options is used to smoothen the input signal. Can be used to eliminate
signal interference as well as to improove signal quality. Setting this option to "1" disables the filter. A higher
setting causes higher smoothening (low pass frequency is 1/n Hz). A setting of 4 suits most applications.
03: units
(options °C, °F, °K, dg, mV, mA, O2, CO, %, ev, mb, m³, m³h, kh, kwh, Pa, AT)
Specifies the unit of the process value
04: trim +/- %
(value range -10.0 to 10.0)
Allows full scale input signal correction. In certain applications it is required to compensate for any deviations
of the installation. Example: Setting this parameter to -5.0% will cause the process value to be trimmed to 95°C
instead of 100°C. Note: This parameter should be used with care since on most applications deviations errors
should to be compensated by eliminating the real cause of the deviation rather then compensating on the
controller
05: offset +/- val
(value range -10.0 to 10.0)
Allows zero offset signal correction. Adjust this parameter if you need to adjust the input offset value. Note:
This parameter should be used with care since on most applications deviations errors should to be
compensated by eliminating the real cause of the deviation rather then compensating on the controller
06: min value
(value range -9999 to 9999)
Minimum value of the process value. Specifies the lower value limit of the process parameter. Any lower value
is respected as underrun (causing an error)
07: max value
(value range -9999 to 9999)
Maximum value of the process value. Specifies the upper value limit of the process parameter. Any higher
