Warning Statement

VDC (DC Voltage)

SEC 3500

The SEC3500 Operator Interface continuously interrogates up to 254 system devices over the 9600 baud

RS485 Modbus Interface. The OI, operating as the Modbus Master, can communicate with any SEC3XXX

Device and any 4-20 transmitter via the SEC3100AIM.

Network devices can be interrogated, configured, and calibrated using the password protected touchscreen user interface.

16 embedded programmable relays provide external device control/interface based on network events.

Additional relays can be located anywhere on the network (groups of 8).

The Statcast RS232 interface continuously scrolls through system operating status. (Read only for the user)

An Ethernet port allows remote access to system screens.

WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR SAFETY

III. OPERATION

The SEC3500 Operator Interface is an intuitive operator interface. For the individual page operations please refer to the following individual instruction manuals on the SEC website:
