Attention! To be able to use the electrical system again to operate the gate after operating
it manually, follow the procedure as described in chapter 10.4.2. “Menu 4.2.1 Closed
position for installing”.
12 EMERGENCY STOP
The HMD230 does not have an emergency stop system. According to the Machine Directive 2006/42/EC,
annex 1, article 1.2.4.3., this is not necessary if the emergency stop system would not lower the risk.
However, an emergency stop system can be connected to the HMD230.
13 MAINTENANCE INSTRUCTIONS
13.1 GATE MAINTENANCE
To ensure the optimum operation of the gate, Heras recommends having maintenance performed by a
qualified engineer at least once a year or after every 7000 cycles.
See the chapter “
SERVICE /MAINTENANCE”
13.2 HMD230 MAINTENANCE
The HMD230 motor drive does not require any maintenance. Only the battery [type CR 2032] for the
integrated clock module must be replaced after 5 years. The battery can be found in a vertical holder
over the twist and selector switch. Beware of causing a short circuit when using a metal implement to
remove the battery.
The entire gate system must be checked regularly, in accordance with DIN EN 12453. To remind the
operating company/user of this necessary maintenance, the
"< MAINTENANCE > necessary" message
is generated by the software of the motor drive.
13.3 CLEANING
The gate and the outside of the drive unit cabinet can be cleaned using a non-aggressive detergent
and a soft cloth, brush or sponge. Avoid using a pressure cleaner as this might damage the gate and
the drive unit cabinet.
Lubricating the running surface of the gate is not allowed.
