Switch Actuator with Secure
15
If there are other devices (e.g. monitor) require to read the communication target value of the relay
during the delay time after power on, then this requirement will be recorded, and then reacted after the
delay time is finished.
If the delay time is long enough, all contacts of the relay can work simultaneously.
NOTE: And considering that it will generate damage to the power system and bus if a lot of
devices operate simultaneously after bus recovery , so it is suggested to set the different delay time
to each device.
Parameter “Sending cycle of "In operation" telegram [1..240,0=inactive]”
The parameter determines the time interval to send the telegram which shows the actuator is
working normally or not via the bus. With the setting “0”, the actuator doesn’t send the telegram; if the
setting is not “0”, a telegram with the value “1” will be sent cyclically according to the setting to the bus.
Options:
0…240s, 0=cyclical send inactive
It is suggested to select the maximum time interval according to the application to keep the bus
load as low as possible.
NOTE: It is starting to count the time after power up, instead of the operation delay after recovery
of bus voltage.
Parameter “Enable Safety priority function”
The parameter is used to set the enable status of the function “Safety priority”.
If it is enabled, 2 “Safety priority” will be activated.
Parameter
“
Safety priority x
”
(x = 1, 2)
There are 2 “safety priorities” for selecting. It is available to define the trigger condition to each
“Safe priority”, and also enable the correspondent communication object “Safety Priority x” (x=1, 2).
These objects are important to the entire relay when under the working mode “Switch Actuator”
and “Heating actuator (without controller)”, but each output can react differently depending on the
received telegrams, whose reactions can be defined in the parameter window “X: Safety”. Options:
Inactive
Reset safety by Object value “0”
Reset safety by Object value “1”
