Note:
In the window “Parameters” of the setting program, column “Access”, the word “NO” designates
parameters that cannot be changed by the user (change of these parameters is blocked).
For actuator with
DMS2 ED electronic system in “Replacement of electro-mechanical board“ design
have two contacts function of
torque switches, two contacts function of position switches and two contacts can
be used according to the customer requirements according to the list below
(typically a function of signalling
switches).
In version
CONTROL have two contacts function of motor relay
(they control the actuator in “open“ and
“close“ position by comparison result of the output shaft of the actuator and input signal),
two contacts have
function of
torque switches or position switches according to setting, two contacts are available to
the customer.
Relay MO, MZ, SO, SZ
In the version Control, the function of relay
MO/MZ is same as that of motor relays.
Their operation is controlled by:
–
regulation loop
(deviation of required and actual position)
–
active errors
Any induced active error will change over both relays to a standstill position
(coils not energized).
In case of
errors, the relays with a function of torque relays
(in both versions DMS2 ED and DMS2 ED Control)
are also
controlled.
List of functions that can be selected for signalling contacts SO, SZ:
