System Start-Up
Careful start–up procedures are essential for proper Mini–PLC–215 Controller
operation. These procedures should be followed after the complete Controller
system has been assembled and installed as described in Section 3.
A cautious approach must be taken toward the initial start–up procedure. Care
and patience during start–up will isolate problems that might occur in the form
of programming errors, wiring mistakes, or equipment malfunction. The
procedures outlined will help the user to uncover problems under controlled
conditions. This will not only make it easier to pinpoint problems but will also
minimize possible equipment damage or personal injury.
In general, checkout procedures are performed in three stages:
Without power applied to the Controller components
With power applied to all devices except those that allow machine motion
with power applied to all devices which are controlled by the User Program.
WARNING: Machine motion during system checkout can cause
injury to personnel or damage to equipment. During the first
stage of checking out the system, disconnect any device that
might cause machine motion to occur when energized.
The following steps must be performed before AC power is applied to the
Controller:
1. Verify that the jumper–selected voltage settings on the System Power
Supply and Industrial Terminal match the incoming AC line voltage. Also
verify that the AC line voltage is within tolerance. For 120V AC
operation, the normal range is 98–132V AC; for 220/240V AC operation,
the normal range is 196– 250V AC.
2. Verify that the proper fuse is in the fuseholder: 1A for 120V AC, 0.5A for
220/240V AC.
3. Verify that the wiring of the main disconnect and Master Control Relay is
correctly installed.
