3.7 Status Outputs
3.7.1 Status Output Signal Convention
Two signal conventions are selectable for the status outputs. The
default convention provides a 24V dc signal when the monitored
input or output is active (closed, high or ON), when the system is
in a Lockout, when there is an I/O-fault, when the system waits
for a Reset, when the output waits for a reset or during an active
mute cycle. If the above conditions are not true, the signal output
would show 0V. Signal convention 2 is the reverse of convention
1, as shown in the table below.

3.8 Commissioning Checkout
After power is connected to the Controller, the EDM has been
properly configured, and the safety outputs have been connected
to the machine to be guarded, the operation of the Controller
with the guarded machine must be verified before the combined
system may be put into service. To do this, a Qualified Person
(see Glossary) must perform the commissioning checkout
procedure described in Section 7.
