b) Error state with the D4 and D3 LED diodes indicating - D4 continuously lighting,
D3 indicates error state with blinking

indication of the "TEST" mode - the EA is put to the position according
to the signal in the "TEST" menu (at connecting the 66 and 86/87
terminals)
2 blinks
(repeating after short pause)
missing of control signal - the EA is put to the position according
to the signal in the "TEST" menu
4 blinks

torque switches activity indication (the EA switched-off with the
torque switches in a mid-position)
5 blinks

failure of the feedback transmitter - the EA is put to the position
according to the signal in the "TEST" menu
7 blinks
(repeating after short pause)
control signal (current at range 4-20mA less than 4mA (3.5mA).
5. Service, maintenance and troubleshooting
5.1 Service
1. In general it is provided that service of the EA is performed by a qualified worker in accordance
with requirement given in Chapter 1!
2. After putting the EA into operation it is needed to verify whether during manipulation any scratch on
surface occurred, it is to be removed to prevent actuator against corrosion!
•
The EA SP/SPR requires just negligible service. Proper putting into operation is a recondition of reliable
operation.
•
The service of the EA leads from the operation conditions and usually resides in information processing for
further arranging of required functions.
•
The stuff has to perform prescribed maintenance to prevent the EA during operation against impacts of
environment, which exceed the frame of allowed influences.
Manual control:
If needed (during adjusting, function checking, failure etc.) the stuff can change setting of the controlled
body using the handwheel. While rotating the handwheel clockwisely the output part moves in the direction
"closed".
Electric local control:
- additional
equipment
In case of need (during
adjusting, function checking etc.),
but
power
supply
must
be
provided, is possible to readjust
actuator by electric local control.
After switching the mode switch to
the mode “LOCAL” it is possible by
the direction switch to control
motion of the output part to setting
direction. Signal lights indicate
achievement of limit position at
relevant direction.
