DE-STA-CO VARI-PAK DC CONTROL - Manual (Page 4)

I. INTRODUCTION
The VARI–PAK Series is housed in a rugged die cast aluminum NEMA 12 enclosure. The
controls are designed specifically for cycling and indexing applications. A variety of models
provide different features and input voltage ratings (see table 1, on page 3). The controls pro-
vide the user with isolated logic functions: STOP, JOG and RUN. Other functions, such as
cycle on demand, can easily be obtained. An important feature of the control is jumper J1
which is used for DC current selection. It automatically presets the IR Compensation and
Current Limit for safe operation on various motors. Standard features include an LED indi-
cator array for “power on,” “stop” and “overload.” Part Numbers 92A61633020000 and
92A61633040000 also contain logic input for “Reverse Run” and “Reverse Jog.” The con-
trols contain trimpots that can be used to readjust Minimum and Maximum speed, Current
Limit and IR Compensation. The front panel contains a built-in 5K ohm speed potentiometer
and a Run, Jog/Stop switch. (See table 3, on page 8, for selectable jumper information.)

ii. SAFETY WARNING! Please read carefully
This product should be installed and serviced by a qualified technician, electrician, or elec-
trical maintenance person familiar with its operation and the hazards involved. Proper instal-
lation, which includes wiring, mounting in proper enclosure, fusing or other over current pro-
tection, and grounding can reduce the chance of electrical shocks, fires, or explosion in this
product or products used with this product, such as electric motors, switches, coils, solenoids,
and/or relays. Eye protection must be worn and insulated adjustment tools must be used
when working with control under power. This product is constructed of materials (plastics,
metals, carbon, silicon, etc.) which may be a potential hazard. Proper shielding, grounding
and filtering of this product can reduce the emission of radio frequency interference (RFI)
which may adversely affect sensitive electronic equipment. If further information is required
on this product, contact the Sales Department. It is the responsibility of the equipment man-
ufacturer and individual installer to supply this Safety Warning to the ultimate end user of this
product. (SW effective 9/2000).
This control contains Start/Stop and Inhibit circuits that can be used to start and stop the
control. However, these circuits are never to be used as safety disconnects since they are not
fail-safe. Use only the AC line for this purpose.
The potentiometer circuit (P1, P2, P3) of this control is not isolated from AC line. Be sure
to follow all instructions carefully. Fire and/or electrocution can result due to improper use of
this product.
!
This product complies with all CE directives pertinent at the time of manufacture.
Contact factory for detailed installation and Declaration of Conformity. Installation of a
CE approved RFI filter (KBRF-200A [P/N 9945C] or equivalent) is required. Additional shield-
ed motor cable and/or AC line cables may be required along with a signal isolator (Camco P/N
99A61455000000).
A label like the one shown, appears on
the top side of your VARI-PAK unit. If
