Overspeed governor EOS
Operating instructions
4.3.5 UCM function (optional)
The UCM function is controlled by the enable move-
ment (ENM1 and ENM2) inputs. The inpust are high-
active inputs which deactivate the UCM function.
Connect X5/3 and X5/6 with X5/1 to activate ENM1
and ENM2 signals that enable movement of the car
(switches UCM function off). When UCM function is
active (ENM1 or ENM2 signal is off), the movement
limited output will be activated as soon as move-
ment has been stopped, that means contact
between X3/1 and X3/2 will be closed.
The correct activation of the UCM function of th
EOS is by accessing the inputs ENM1 and ENM2
through two independent signal generators. The
EOS checks the synchronization of the inputs and
generates a secure condition (opening of safety cir-
cuit at next stop) if a discrepancy is detected.
It is possible to use one secure signal gen-
erator, only in this case the inputs ENM1
and ENM2 can be connected directly to
each other and the signal generator.
4.3.6
Direction indicator (optional)
The connector X4 provides a signal depending on
rotation direction on pin X4/3 and a signal depend-
ing on speed on X4/1. Signal load has to be con-
nected between X4/1 and supply voltage as well as
X4/3 and supply voltage (see 4.1.3).
Supply voltage has to be below 32VDC and 100mA
for each channel.
When the direction indicator option is
ordered the error indicator (4.3.9) is disabled.
4.3.7
Encoder interface (optional)
Connector X4 provides two 90 degree phase shifted
open collector output signals ENC_A, ENC_B and a
ground pin (X4/2) which is internally connected to
the negative supply voltage pole (X5/2). Signal load
has to be connected between X4/1 and supply volt-
age (for ENC_A) and X4/3 and supply voltage (for
ENC_B). Supply voltage may be up to 32 VDC.
One revolution of the governor wheel (360°) causes
2 4 0
state changes on the signals ENC_A and
ENC_B, which means 60 periods with 4
states each.
When the encoder option is ordered the error indi-
cator (4.3.9) is disabled.
