Attention: If the gate is disengaged from the motor drive and moved to
another position by hand, the closed position of the gate must be
redefined in the program before using the motor drive again.
6.4 RELAY OUTPUT CONNECTIONS
The HMD230 has five relays available for signalling and lighting purposes
(Illustration 25:). Relays Rel1 to Rel3 are make contacts, the other two relays
(Rel4, Rel5) are make-and-break contacts. The switch contacts are potential free
and are capable of ohmic loads of up to 250 W. Connecting these relays, also as
described in chapter 6.4.1 and 6.4.2, can also be done on the backplane; see
appendix B and C.
A fused 230V output is available to connect AC loads to the power supply of the
HMD230 (Illustration 24:). The wiring from this output to the relevant relay must
be installed by a professional.
The following functions have already been set on the relays:
