Ametek Gemco 1996 Ram-Set Manual de instalação e manutenção
6. Press Type: Select the type of press: (if applicable)
Note: If option 1 or 2 is picked, the 110VAC from the slide gap switch must be connected to Ram-Set per Wiring Diagram
E-0204800-C.
7. Offset: With keyswitch in program position, depress jog-up key. Jog past the upper
mechanical overtravel limit to the upper maximum mechanical position. Determine this value (measure or use press manu-
facturers data) and enter value into Ram-Set offset. This will assure a consistent measurement format even when changes
are made.
Note: Please also note that offset can be set any known slide position.
8. Upper Limit: The electronic limits of the Ram-Set should be used in conjunction with
the existing press mechanical overtravel limits. To set the upper electronic limit, jog the slide down past then back to the
existing slide upper limit switch. Read the Ram-Set display and program this value as the electronic upper limit setting.
9. Lower Limit: Jog slide to existing press mounted lower limit switch. Read the Ram-
Set display and program this value as the Ram-Set lower electronic limit setting.
10. Slow Dwell: The slow dwell settings are the method the Ram-Set uses to precisely
position the slide. These time based dwells (on/off) are attached to the up/down output relays, and are enabled in the auto
mode when the slide enters the slow down zone. The amount of time the on/off dwells should be enabled varies from
system to system, but the idea is to enable the on dwell long enough to energize the slide adjust motor starter, and the off
dwell long enough for the slide to coast to a stop.
Slow dwell can be programmed from .01 to 9.99 seconds. A good typical value for the time on a dwell is .40 seconds.
Program time off for slow dwell. This function, more than any other, determines the repeatability of the automatic position-
ing. It is typically set at .60 seconds.
11. Slow Down Setpoint: Set the deceleration distance or slow down entry point. This
is the point at which the system will begin to pulse the output to the Ram adjust motor starters. It is designed such that
the system will drive toward the setpoint from below in all cases. If the ram is above the setpoint, the system will drive
below the setpoint by the width of the down setpoint, stop for 3 seconds, and drive up to the programmed shut height.
This method serves two purposes: one, to take the backlash out of the ram adjust system; and two, to gain consistency
in adjustment by driving at the setpoint in one direction at all times.
