Relay control After having entered the operator address and its confirmation (E key), the password
is requested. After having entered the password, the question for the control of the re-
lay appears again. After having confirmed again with the E key, the action is carried
out. If a relay could not be deactivated, for example because an annunciation config-
ured to it is active, this is acknowledged with a negative feedback.
 The operator addresses for the control of the other relays are stored on the subse-
quent addresses. In the case of an operation via the membrane keyboard, a once
entered password is memorized until the address block is left. In the case of an op-
eration via DIGSI, the password has to be entered again for each control action (re-
lay on or off).
