E-Stop Safety Relay
– Model ES-TA-3D1
4.5 Selecting the Autobaud Feature
The ES-TA-3D1 has an autobaud feature which allows for automatic recognition of the
baud rate on the network into which the ES-TA-3D1 is installed. This convenient
feature automatically matches the ES-TA-3D1 baud rate to the network without
requiring a baud rate configuration step. The autobaud feature is set to ON at the
factory. When the autobaud parameter is set to ON, the baud rate parameter may not
be set via the DeviceNet network. The autobaud parameter may be turned off by
setting the DeviceNet autobaud parameter to OFF (see the EDS file for path
information). When the autobaud parameter is set to OFF, the baud rate parameter
may be set via the DeviceNet network to the desired baud rate.
To determine if autobaud is set to ON, power (at the DeviceNet power inputs) the
ES-TA-3D1 while it is not connected to the DeviceNet network; the Bus Status
Indicator will flash green, then red, then OFF in a repetitive sequence. If autobaud is
set to OFF, then the Bus Status Indicator will flash green (or red) after the initial
green/red sequence at power up.
4.6 Initial Checkout Procedure
1)
IMPORTANT: Ensure that there are no connections at terminals 39/19 and
40/20.
2)
Close all E-stop inputs. Ensure all monitoring inputs are closed and that the
Reset input is open. (Refer to Figure 3.)
3)
Apply input power to the E-stop relay at terminals 1 and 21. Verify that K1,
K2 and Reset indicators are OFF. Verify that all E-stop and monitor indicators
are ON. (If Auto/Manual Reset selector is set to Auto mode, verify K1, K2
and all E-stop indicators are ON. Reset and all monitor indicators are OFF.)
4)
Close the Reset input (if Auto/Manual Reset selector is set to AUTO mode,
go to step 5). Verify that the Reset and K1 LED indicators go ON. K2
indicator should remain OFF. Open the Reset switch and verify that the Reset
indicator is OFF. The K1 and K2 indicators should both be ON at this time. If
the K2 indicator comes ON before the Reset switch is opened, disconnect
the input power and check all wiring. Return to step 2 after the cause of any
problem has been corrected.
5)
Activate one Emergency Stop switch (open its contacts). The K1 and K2
indicators should turn OFF, simultaneously. If either indicator does not go
OFF, check the E-stop indicators. (The indicators for the activated Emergency
Stop switch should be OFF, as well as indicators for E-stops with higher
numbers. For example, if E-stop #3 is activated, the indicators for #3, #4, #5,
and #6 should all go OFF simultaneously.) If all E-stop indicators are OK but
either or both K1 and K2 indicators are ON, disconnect the input power and
check all wiring. Return to step 2 after the cause of the problem has been
corrected.
6)
Repeat the above checkout procedure for each E-stop switch, individually
(ES1 through ES6).
IMPORTANT . . .
Check Each Switch
Individually
Check ALL Emergency
Stop switches, individually, during
each checkout procedure. When two
or more Emergency Stop switches
are used, each switch must be
individually actuated (engaged), then
re-armed and the ES-TA-3D1 reset.
This allows the ES-TA-3D1 to check
each switch and its wiring to detect
faults.
