Control Relays on the FLEX /
FLEX Walker
All of the components on the FLEX and FLEX Walker are isolated from the PLC. When we say
isolated, it means there is a control relay between the PLC and the motor or device. This is
to protect the PLC against power spikes from motor amp loads that can cause damage to
the smaller internal PLC relays.
The FLEX machine is equipped with 10 replaceable control relays and the
FLEX Walker has
15 replaceable relays
that operate ALL the motors of the machine. The Vacuum Relay (CR19)
and Power Relay (CR20) are located on the bottom side of the electrical panel.
