TCM Operation Manual
Millimeters per Minute
When the
mm
indicator is illuminated, the units for the crosshead speed (as indicated on the Speed Indication Display) will be in millimeters
per minute.
Inches per Minute
When the
in
indicator is illuminated, the units for the crosshead speed (as indicated on the Speed Indication Display) will be in inches
per minute.
Compression
When the compression arrow indicator is illuminated, the crosshead will move in the compression direction when the Start/Stop button is
depressed. (See Modes of Operation below).
Tension
When this the Tension arrow indicator is illuminated, the crosshead will move in the tension direction when the Start/Stop button is depressed.
(See Modes of Operation below).
MODES OF OPERATION
Note:
In all modes, when a DFG is connected to the TCM and a DFG set Force Limit is reached, the TCM will stop and the Message “Load” will be displayed.
Compression-Standard
When only the Compression indicator is illuminated, this indicates the
Compression-Standard
mode of operation. In this mode, the crosshead will
move in the compression direction (at the speed indicated on the display) when instructed to do so by pressing the Start/Stop button. It will automat-
ically continue in this direction until it reaches the adjustable limit switch position. If the mechanical limit switch is reached, the display will show
BOT
and the
Set Speed to indicate that the lower (bottom) travel limit switch has been reached. Further, if a force gauge was set to
XMIT LIMIT
(transmit a force limit), the
TCM will stop when a low signal is sent over the serial port. The XMIT will stop the TCM only when connected to the Test Stand using the XMIT cable (SPK-
TCM-018) into the DFG Port.
When moving in the compression direction, the display will flash alternatively between
DN
and the current speed.
Tension-Standard
When only the Tension indicator is illuminated, this indicates the
Tension-Standard
mode of operation. In this mode, the crosshead will move in the
tension direction (at the speed indicated on the display) when instructed to do so by pressing the Start/Stop button. It will automatically continue in this
direction until it reaches the adjustable limit switch position. If the mechanical limit switch is reached, the display will show
TOP
and the set speed to indicate
that the upper (top) travel limit switch has been reached. Further, if a force gauge was set to
XMIT LIMIT
(transmit a force limit)
,
the TCM will stop when a high
signal is sent over the serial port. The XMIT will stop the TCM only when connected to the Test Stand using the XMIT cable (SPK-TCM-018) into the DFG Port.
When moving in the tension direction, the display will flash alternatively between
UP
and the current speed.
