This product should be installed and
serviced by a qualified technician,
electrician or electrical maintenance
personnel familiar with its operations
and the hazards involved. Proper in-
stallation (see instruction information
which accompanies product), which
includes wiring, mounting in proper
enclosure, fusing or other over cur-
rent protection and grounding, can re-
duce 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 protec-
tion must be worn when working with
control under power. This product is
constructed of materials (plastics,
metals, carbon, silicon, etc.) which
may be a potential hazard. Individual
material safety data sheets (MSDS)
are available upon request. 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 information
is required on this product, contact
our factory. It is responsibility of the
ultimate user of this product to read
and comply with this safety warning.
(SW effective 1/89).
***IMPORTANT***
YOU MUST READ THESE
INSTRUCTIONS BEFORE
OPERATING CONTROL
1. Be sure AC line voltage
corresponds to control voltage.
2. Install the correct Plug-In
Horsepower Resistor according
to armature voltage and motor
horsepower.
3. Recheck connections: AC line to
L1 and L2; armature to A+ and
A– and field (Shunt motors only
to F+ and F-.) (Note: If motor runs
in improper direction, interchange
armature leads.)
4. Install proper AC line fuse and
armature fuse as required.
5. Nominal trimpot settings are as
follows (expressed in % of full
CW rotation):
Safety warning – pleaSe read carefully
TABLE 1: NOMINAL TRIMPOT SETTINGS
RAMM Solid State DC Motor Speed Control
A Plug-In Horsepower Resistor must be installed to match the RAMM to the motor
horsepower and voltage. See table 2 for the correct value. Plug-In Horsepower
Resistors are stocked by your distributor.
TABLE 2: PLUG IN HORSEPOWER RESISTOR CHART
Plug In Horsepower Resistor
* Motor horsepower and armature voltage must be specified when ordering so that proper
resistor will be supplied.
** For overlapping motor horsepower range use lower value Plug-In Horsepower Resistor.
*** Auxiliary heat sink must be used to achieve HP rating.
MIN (minimum speed):
15%
CL (current limit/torque):
65%
MAX (maximum speed): 65%
ACCEL (acceleration start): 20%
IR (IR compensation):
25%
DECEL (deceleration stop): 20%
