Protection and alarms 6. the pins must be short circuited Free potential contacts are available for alarms if a controller SYS 3000 is not used in the system Information concerning the system status are displayed on the ARCON STM 150 LCD: the load position (mains or inverter). It is only activated for customers in chronic state of overdue payment.3. Payment protection Payment protection is deactivated when the ARCON STM leave the factory. Remote control and ARCON STM free potential contacts. 6. The protection only can be deactivated introducing the apposite code the customer can get from CE+T after payment (each inverter has its own code). When the protection is activated.4. 6.

When the protection is deactivated it becomes quite invisible for the user. A remote control is available on the connector located on the rear side of the unit Function is to Start / stop remote of inverters via external potential free contact If the remote ON / OFF switch is not used. 6. the message “limited working” is displayed every 5 seconds.

Troubleshooting guide With an ARCON STM 150 the system can only start switching “ON” the local switch of the ARCON STM but only after the local ON push button of each inverter is switched ON. the unit has to return in factory for inspection: please contact your supplier. The errors list gives the various reasons to display alarms messages. 7. Alarms and display status (Messages list) The unit ARCON STM 150 can take a decision to transfer the load on the emergency source for internal or external reason.
