Actual signals and parameters 279
4019 ACT1
MAXIMUM
Defines the maximum value for variable ACT1 if an analog
input is selected as a source for ACT1. See parameter
4016
ACT1 INPUT . The minimum ( 4018 ACT1 MINIMUM ) and
maximum settings of ACT1 define how the voltage/current
signal received from the measuring device is converted to a
percentage value used by the process PID controller.
See parameter
4018 ACT1 MINIMUM .
100%
-1000…1000% Value as a percentage 1 = 1%
4020 ACT2
MINIMUM
See parameter 4018 ACT1 MINIMUM . 0%
-1000…1000% See parameter 4018 . 1 = 1%
4021 ACT2
MAXIMUM
See parameter 4019 ACT1 MAXIMUM . 100%
-1000…1000% See parameter 4019 . 1 = 1%
4022 SLEEP
SELECTION
Activates the sleep function and selects the source for the
activation input. See section
Sleep function for the process
PID (PID1) control on page 155 .
NOT SEL
NOT SEL No sleep function selected 0
DI1 The function is activated/deactivated through digital input
DI1.1 = activation, 0 = deactivation.
The internal sleep criteria set by parameters
4023 PID
SLEEP LEVEL and 4025 WAKE-UP DEV are not effective.
The sleep start and stop delay parameters 4024 PID SLEEP
DELAY and 4026 WAKE-UP DELAY are effective.
