Conformance to EC Directives
H Applicable Directives
S EMC Directives
S Low Voltage Directive
Concepts
EMC Directives
EMC Directives stipulate that the system must comply with both EMS and EMI standards
(see the following note). Because OMRON devices are designed for installation in various
equipment or machines, they comply with the relevant EMC standards so that the equipment or machines can easily comply with the EMC standards. However, the systems used
by customers are diverse, and EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions
of the equipment or control panel in which the OMRON devices are installed. The customer
must, therefore, perform final checks to confirm that devices and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
Always ensure that devices operating at voltages of 50 to 1,000 V AC or 75 to 1,500 V DC
meet the required safety standards (EN61131-2).
Conformance to EC Directives
The 3F88L-160/162 Cam Positioner complies with EC Directives. To ensure that the system in which
the 3F88L-160/162 is installed complies with EC Directives, the following precautions must be observed.
1. The 3F88L-160/162 is defined as an in-panel device according to the Low-voltage Directive.
The 3F88L-160/162 must, therefore, be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power supplies used as
I/O power supplies.
3. The 3F88L-160/162 conforms to the Common Emission Standard (EN61000-6-4) in relation to EMI. However, the radiated emission (10-m regulations) may vary depending on the
configuration of the control panel, connected devices, wiring, and other conditions. The user
must, therefore, confirm that devices and the overall machinery conform to EC Directives.

TermMeaning
Cam outputCam output consists ON/OFF outputs for the Resolver angle according to
the ON/OFF angles set by the user (the cam program).
Cam programA cam program consists ON/OFF angle data set by the user.
Cam protectThe cam data protect function protects the cam ON/OFF data from being
inadvertently changed or deleted.
Compensation operationWhen in RUN mode, this function can be used to adjust the cam output ON
and OFF angles by using the operation keys in order to check mechanical
operation.
Origin compensationWhen in SET mode, the mechanical origin and the Resolver origin can be
aligned by pressing the ADJ switch on the front of the Cam Positioner.
Origin shiftWhen in RUN mode, this function can be used to temporarily shift the
displayed angle to the origin by shorting the TRIG terminal with the 0-V
terminal.
Origin valueThe origin value is a value set as the origin of the Resolver. This value can
be set to any angle when origin compensation or origin shift has been
performed. The default setting is 0.
ResolverThe Resolver is a sensor that detects the absolute angle. One of four
Resolver models (3F88L-RS17, 3F88L-RS17T, 3F88L-RS15, and
3F88L-RS15W) can be selected for 3F88L-160 and 3F88L-162 Cam
Positioners.
Trial operationWhen in PRGM mode, this function can be used to adjust the cam output
ON and OFF angles by using the operation keys in order to check
mechanical operation.
The greatest difference from compensation operation is the ability to adjust
the ON and OFF angles of any bank or cam number without any external
control signal input during trial operation.

WARNINGTake safety measures outside the Cam Positioner to ensure safety for the entire
!
system in the event of Cam Positioner failure or error caused by factors external to
the Cam Positioner.
Faulty operation may result in a serious accident.
S Emergency stop circuits, interlock circuits, limit circuits, and similar safety mea-
sures must be included in control circuits outside the Cam Positioner.
S The Cam Positioner turns OFF all outputs when its self-diagnostic function detects
an error (ERROR is OFF), when TRIG input turns ON, or when RESET input turns
ON. Take safety measures outside the Cam Positioner to ensure safety for the entire system in such an event.
S The Cam Positioner output may remain ON or OFF due to damage to an output
transistor or for some other reason. Take safety measures outside the Cam Positioner to ensure safety for the entire system in such an event.
