About this Manual:
The manual describes the operation of the E5AF/E5EF Fuzzy Temperature Controller and includes
the sections described below.
Please read this manual completely and be sure you understand the information provided before at-
tempting to operate the Fuzzy Temperature Controller.
Section 1
introduces the basic features of the E5AF/E5EF Fuzzy Temperature Controller’s front pan-
el and a brief description of its remote mode and local mode.
Section 2
gives a general description of the E5AF/E5EF Fuzzy Temperature Controller’s rear panel
communications connector/terminals.
Section 3
provides the interface specifications and basic operational elements required in order to
use the RS-232C/RS-422/RS-485 Controllers and also provides the header codes.
Section 4
provides the basic operational elements required in order to use the BCD Output Models
and also gives two examples of its use.
Section 5
describes the connections and settings of the Transmission Output Models.
Appendix A
provides an ASCII list.
Appendix B
provides a list of optional accessories.

2--2 Connecting Communications Connectors/Terminals
Connect a host system or peripheral device to the appropriate communica-
tions connector; confirm that the system or device conforms to that connec-
tor’s communications specifications. Before mounting the Fuzzy Temperature
Controller, be sure to consider the added depth required by connected
cables.
Panel

Depth of the main body from panel when mounted
*1: Without OMRON XM4

100 mm No less than 170 mm (25-pin connector)
No less than 160 mm (9-pin connector)
The following OMRON D-sub Connectors are recommended:
25 pin: XM4A-2521 (plug) + XM2S-2511 (hood)
9 pin: XM4A-0921 (plug) + XM2S-0911 (hood)
If using an equivalent connector, make sure that the connector screws are
the following metric size: M2.6 x 0.45 mm.
Section 2--2
3
Securely insert the communications connector from the external system into
the communications connector on the Temperature Controller. After connec-
tion, tighten the screws on either side of the communications connector with
a screwdriver.
When connecting communications via terminal blocks, use crimp-style termi-
nals of the appropriate size for use with M3 x 8 mm connector screws.
65.8 max.
For the appropriate cable length, refer to the respective communications
specifications.

Connection method (RS-232C direct connection): 1:1 connection only
A carrier detect (CD) signal for the host computer is not supported by the
E5AF via its RS-232C port since the E5AF’s RS-232C is defined as DTE
(Data Terminal Equipment). If a CD signal is needed, it must be provided a
the host computer.
