Test position feedback (TPF)

Description
You can carry out the "Cold run" function test using the "Test Position Feedback (TPF)"
function block. For this purpose, the function block input (plug) must be connected to the
respective socket. The activated test position will be indicated by the flashing QL of the
control function.
The "Test Position Feedback (TPF)" function block consists of
● one plug
● a "Status - test position" socket. It is set if a signal is pending at the input.
● one "Fault - test position feedback error" socket. It is set when
– "TPF" is activated although current is flowing in the main circuit
– "TPF" is activated and current is flowing in the main circuit.
In total, one "Test Position Feedback" function block is available.
Note
When the test position is enabled, the QLE / QLA sockets of the control function are
activated, to indicate test operation of the motor feeder via a flashing button LED, for
example.
