Introduction
The MCS2000-DRV2 Dual Channel/Dual Voltage
drive is a replacement for the MCS2000-DRV and
MCS2000-DRVH Drivers in one unit. The unit is
designed so that it can operate from either 24 volts
DC input or 48 volts DC input and provide output
voltage and current for operation of any of the 24
volt DC tension brakes available from Warner
Electric.
The universal design replaces two separate drivers in
one package and provides for dual brake operation,
for either single brake when only one brake is
required or dual brake operation on splicer systems
where two brakes are required.
The driver can be controlled by any of the MCS2000
controllers offered as either a single channel system
or dual channel system. The MCS2000-ECA,
MCS2000-CTDA, or MCS2000-CTLC controllers can
provide the operating signals.
The MCS2000-DRV2 has reduced input terminals on
the front of the unit that are pluggable which will
make installation and wiring much easier than the
previous versions. By using a pluggable terminal
block, if replacement is required then only the
controller has to be disconnected and removed and
a new controller installed without having to rewire the
entire system.
Footprint for the DRV2 is identical to that of the
MCS2000-DRV and MCS2000-DRVH drivers. The
MCS2000-DRV and MCS2000-DRVH can be
replaced with the MCS2000-DRV2 without having to
make any mechanical changes in the mounting
footprint.
Additionally, LED indicators on the face of the control
make troubleshooting and monitoring operation
much simpler than previous versions. A combination
red and green LED for each channel determines
operation during normal run conditions as well as
during faults.
Each driver channel has its own individual
anti-residual adjustment to make brake adjustment
in the “off” state optimum. Anti-residual provides a
reverse current to the brakes in the off state to
minimize residual magnetism build-up. This allows
for reducing the drag torque in the brake during
initial start-up.
