13: output char.
Specifies the operation range of the output. Used to assign an output to either
heating range, cooling range or both rances. Typically the heating output is set to
"0 to +100%" and the cooling output (eg. for controlling a fan) is set to "0 to
100%". Both outputs assigned to the same control loop. The available settings are
0=0% to +100% / 1=+100% to 0% / 2=0% to 100% / 3= 100% to 0% / 4= 100% to
+100% / 5=+100% to 100%
14: outp.% on IDLE
Whenever the controller is IDLE the output provides this value
15: outp.% on ERR
Whenever the controller is in ERROR status the output provides this value. Note
that this only applies on system errors and not an operation error on a single loop
16: travel time
Enter the time (in seconds) for the servomotor to operate a complete cycle from
fully close to fully open
17: delay 1/10s
Delay time of the servomotor on direction changes. This parameter (given as
100ms units) is used to compensate for gearbox lags etc.
18: update time
Rate in seconds the servomotor position is updated. Decreasing this rate causes
more stress to the servomotor
19: hyst. %/steps
Hysteresis for updating the servomotor position. Decreasing this rate causes more
stress to the servomotor. In most application a hysteresis of 1% is recommended
20: compare mode
Selects the kind of equation of the equation given as limit 1 ? limit 2 + limit const.
The "?" stands for ">=", 1 stands for "<=", 2 is "limit 1 limit 2 less then limit const",
3 is "limit 1 limit 2" more than limit const. Add 4 to disable signal during SKIP. The
digital output is ON when the equation is true. Example: To activate the output

(options 1>2+c,1<2+c dif<c, dif>c)
whenever the actual temperature exceeds the setpoint more than 30°K (= over
temperature alarm) set the parameters as follows: compare more = 0 / limit 1 =
IN00 / limit 2 = SP00 / limit const = 30
21: limit 1
Selects the process value used as "limit 1" in the equation. Can be a setpoint, an
actual temperature, a loop (loop) output or "OFF" to insert "0" in the equation. For
detailed explanation including an example refer to "compare mode"
following parameters apply on selection LIM only:
22: compare mode
Selects the kind of equation of the equation given as limit 1 ? limit 2 + limit const.
The "?" is replaced depending on this parameter: 0 stands for ">=", 1 stands for
"<=", 2 means "limit 1 limit 2 less then limit const", 3 means "limit 1 limit 2"
more than limit const. Add 4 to disable sigal during SKIP. The digital output is ON
when the equation is true. Example: To activate the output whenever the actual
temperature exceeds the setpoint more than 30°K (=overtemp. alarm) set the
parameters as follows: compare more=0/limit 1=IN00/limit 2=SP00/limit const = 30
23: limit 1
Selects the process value used as "limit 1" in the equation. Can be a setpoint, an
actual temperature, a loop (loop) output or "OFF" to insert "0" in the equation. For
detailed explanation including an example refer to "compare mode"
24: limit 2
Selects the process value used as "limit 2" in the equation. Can be a setpoint, an
actual temperature, a loop (loop) output or "OFF" to insert "0" in the equation. For
a detailed explanation including an example refer to "compare mode"
25: limit const
The constant value used as "limit const" in the equation. For detailed explanation
including an example refer to "compare mode"
26: output on IDLE
Defines the state of the digital output when the controller is IDLE: 0 = same as
during programme run / 1 = OFF / 2 = ON
(value range OFF, SP00 to CH19)
(options 1>2+c, 1<2+c, dif<c, dif>c)
(value range OFF, SP00 to CH19)
(value range OFF, SP00 to CH19)
(value range 99 to 1999)
(value range 0 to 2)
