WARNING
Risk of injury due to electric shock.
• For the electrical power supply, use only PELV circuits in accordance with IEC
60204-1/EN 60204-1 (Protective Extra-Low Voltage, PELV).
• Observe the general requirements of IEC 60204-1/EN 60204-1 for PELV circuits.
• Only use voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.

6.6 STO interface [X6]
The STO safety function is described in detail in the EMCA-EC-S1-… document. The
STO function should only be used in the manner described in this document.
Recommendation for initial motor start-up without safety engineering:
–
minimum circuitry with emergency stop switching device
–
two-channel switch-off via control inputs STO1 [X6.4] and STO2 [X6.5]
[X6] Pin Description
1 NC1 Acknowledgement contact:
–
potential-free
–
low impedance if the STO function has been
requested and activated via 2 channels.
2 NC2
3 +24 V DC
LOGIC OUT Logic voltage output (from [X4.1]), reference potential
(0 V) is pin [X6.6] or [X4.2] (internally bridged)
Not overload-proof! Max. 100 mA permissible.

6.9 External battery [X10] - only EMCA-EC -...- 1TM
[X10] Pin Description
1 B Connection for external battery (position changes are
recorded for a maximum of 7 days (best case) without
supply voltage and without battery (after charging for
approx. 24 hours)). With the EADA-A-9 battery from
Festo, the duration can be extended to a maximum of
6 months.

7 Commissioning
The product communicates with a connected PC with the TCP/IPv4 protocol.
Establishing network connection – example “point-to-point connection”
Requirement:
–
The PC is configured as a DHCP client (usually standard for PCs).
–
The EMCA is configured as a DHCP server (factory setting).
–
At initial commissioning connect the EMCA directly to the PC.
Factory setting
DHCP server: active
IP address: http://192.168.178.1
Subnet mask: 255.255.255.0
Gateway: - (a gateway is not assigned.)
Web servers
The integrated web server provides read access to an English-language website.
FCT (Festo Configuration Tool)
The EMCA plug-in for the Festo Configuration Tool (FCT) supports all the steps
necessary for commissioning of the device.
Observe the documentation for the product è www.festo.com/sp.
Before switching on the power supply:
Check installation:
–
Check all connections.
Check readiness for operation
1. Make sure that controller enable signal is switched off (pin X9.4).
2. Switch on the power supply. The OK LED on the front panel of the device
should now flash green.
If the OK LED stays off, the device is not ready for operation. If the ERROR-LED
shows red, an error is reported and the cause of the error must be remedied.
