A single row six pole terminal block (Figure 3-16) is located on the rear panel for remote control of Leader
/ Auxiliary configurations and Emergency Stop.
FOLLOWER and FCOM are used to remote control each system to configure for Leader or Follower
operation. When 24V DC is applied to the FOLLOWER and FCOM, the system is configured in
FOLLOWER operation. When 24V DC is removed, the unit operates in LEADER mode.
ESTOP and ECOM are used to remote control an Emergency shut off switch. This connection is required
to create an OR-ed operation of more than one –ES switch. When 24V DC is applied, the unit’s output is
Enabled (ON). When 24V DC is removed, the unit’s output is disabled (OFF). Note that ESTOP
connection is required for each individual chassis. ESTOP results in disabling voltage directly to the
amplifiers.
