4.1.3 Electrical Installation of Controller LPC-2000.1 for Standalone Operation
For standalone operation the LPC-2000.1 is disabled when power is turned on. It can be enabled manually by
using the “UP” button on the display. If the controller shall be enabled automatically, when power is applied
the “ENABLE” pin on the “User Interface” connector (see Table 14) has to be active (typically 24V).
4.1.4 Electrical Installation of Controller LPC-2000.1 for Extended Operation
If the LPC-2000.1 shall to be controlled with external signals the “User Interface” can be used with the PIN
designations described in Table 14.
