4.2 PowerOff Adjustments Ċ There are a number of
static adjustments that are to be made in order to tailor
the controller for a specific drive's needs. This work may
only be performed when the aĆc line power is removed
at the main disconnect switch. Also, these steps should
be carried out by an individual who is familiar with elecĆ
tronic equipment.
4.2.1 Controller Inspection Ċ The object of this inĆ
spection is to be sure that the Modification Kits are propĆ
erly mounted and connected with the Regulator Module.
Full details of the Kits are included in Section 6.
Step 1 Ċ Open the Cover of the controller. Be sure to lift
it directly up about 2 inches (50 mm) before swinging the
Cover on its hinges.
Step 2 Ċ Inspect the Regulator Module. By gently pressĆ
ing a corner, determine that it is firmly seated on its supĆ
ports. Gently press all plastic connectors that mate with
the Module. If any are loose, seat them firmly. If any are
unseated, connect them.
Step 3 Ċ Inspect all plugĆin Modification Kits. Test each
for a firm mounting condition.
Each should be mechanically connected to the RegulaĆ
tor Module by means of a mounting post screw. Each
should be electrically connected to the Module by a seĆ
ries of parallel pins. If any of the pins are bent, improper
operation results. Examine the pins to make sure they
are perfectly parallel. Only one pin may fit through a hole
in the Kit.
Step 4 Ċ Inspect all screw terminal connections on the
Modification Kits. Make sure the wires are firmly conĆ
nected. Also make sure that there is enough insulation
on the wires to prevent a short between the conductors.
Step 5 Ċ Inspect the signal wiring from the Operator's
Control Station. If a Local Station is used on the Cover,
there are two connectors that mate with the Regulator
Module at pins 32 (RED) and 28 (GRN). (See Figure 4.2.)
