APPENDIX 2. DESCRIPTION ON CONTACT SIGNAL COMMUNICATION
1. Outline
2. Contact Signals Entering the e-Line Connector
The following two types of contact signals are used in the
Chromaster series.
(1) Contact signals (START, ERROR, BUSY) entering the e-
Line connector.
These are contact signals having input/output functions that
are used in common for each unit. These signals are
respectively formed from the START (IN/OUT), ERROR
(IN/OUT), and BUSY (IN/OUT) lines.
(2) Individual contact signals used by each unit.
These are contact signals that are input and output via 3-
pin connector. Their names and functions vary with the
unit. A name that indicates the function is given at each
connector.
 Example of output contact signal: EVENT of pump
 Example of input contact signal: LAMP OFF IN of
detector
Each unit has two e-Line connectors for connection at the rear of
the main unit, and the signals of each unit in series via the e-Line
cable, synchronism of the Chromaster series system can be
easily achieved.
For obtaining synchronism with the L-2000 series and
D-2500 by way of contact signals, use the cables listed below for
the connection.
