M1050-PLS
AVG Automation's PLS and Mini-PLS families have continually set the standard for speed, precision, reliability, and product features in the Programmable Limit Switch (PLS) marketplace. While retaining the key features and high-standards of other AVG Automation products, the M1050 combines 10 power outputs, fault detection and indication, eight userdefined PLS programs, and simple, easy-to-learn programming, in one compact unit with a NEMA 12 front panel. In addition, each of the eight PLS programs supports up to 80 ON/OFF setpoint pairs for 8-channel units, or 160 for 16channel units, which may be used in any combination per eight output channels. Included is a fault output which indicates on the display the source of the fault for fast, easy troubleshooting and a motion detector which energizes when the resolver is rotating between the HIGH and LOW user-programmed limits.

Simultaneous display of related parameters for easy understanding
In the normal operating mode, the large, 0.56" (14.2 mm) numerical display indicate the selected PLS program number, the selected channel number, and the current resolver RPM and position. When programming PLS setpoints, the display shows the program number, selected channel number, and the selected ON and OFF setpoints.
In all modes, bright easy-to-read bar graph displays the TRUE output status of all eight or 16 PLS outputs, as well as the fault relay status, the motion output status, and the external program select enable input status. |

Powerful, Easy-to-Learn, Human-Machine
AVG Automation's
human factors engineering has made it possible to program all PLS
functions with only five front panel keys and a smart front panel
display:
With
these five self-explanatory programming keys, programming the
M1050 is extremely simple. No long complex key sequences to
remember.
Patented Up & Down Arrow Keys for Fine-Tuning
in Motion
All programmed values, except Scale Factor and the PLS program
number, can be adjusted with the machine running, making fine-tuning
of job parameters easy. Two fully isolated supervisory inputs
prevent accidental or unauthorized program changes.

High-Speed
Operation
The M1050 PLS can operate up to 1800 RPM while maintaining a
timing accuracy of less than 100 µs.
Multiple
Program Storage Makes Job Changeover Easy The
M1050 PLS can store up to eight independent, user-defined PLS
programs for different machine setups. The M1050 is easily
configured to accept either front panel or external PLCcompatible
input to select a program.
Built-in
Speed Compensation for All PLS Outputs
The M1050 PLS
features a rate offset to compensate for speed variations. This
rate offset represents a positive number that varies linearly with
RPM. The rate offset is added to the resolver position and is
used to advance the PLS settings as a function of the machine
speed. In M1050, the rate offset can be programmed in Scale Factor
units per 10 or 100 rpm, depending on model, up to full Scale
Factor value.
Built-in
Tachometer and Motion Detector
The built-in tachometer and motion detector are accurate to 1 rpm
and are updated over 68 times per second to provide fast, accurate
indication and detection of rotary motion. The motion detector is
programmed to energize a power relay output when the machine's RPM
falls between the low or under-speed limit and the high or
over-speed limit. The motion detector output status is always
indicated on the front panel.
Built-in
Fault Detector
The fault output is normally energized when the M1050 PLS is
operating properly and the resolver wiring is intact. If an
internal M1050 fault is detected, or the power fails, or one or
more of the resolver wires is broken or disconnected, the fault
output will de-energize. Under fault conditions all PLS outputs
and the motion output will de-energize.
Brake
Monitor Option
The M1050 Brake Monitor measures the time it takes to bring a
rotating machine shaft to a full stop. If the shaft fails to stop
within specified safety limits, Caution or Danger outputs are
turned OFF. If the shaft stops safely in time, the Safe output
turns ON.
