Large Displays OC57-T
with 57mm, 100mm or 125mm display size. The
timer function is controlled with external signals at
three inputs START, STOP and RESET.
The keyboart at the rear permits the selection of the
desired display format:
99.59.59 HH. MM. SS
999999 Seconds
9999 S Seconds
999.9 M Minutes with decimal format
999.5 M Minutes with 60 format
59.59.99 MM. SS.
The display has six red high intensity digits with
decimal points. The aluminum cabinet is for panel or
wall mount and is IP65 screened at the front.
The keyboard and the I/O connectors are placed at
the rear panel.
The large displays are made as Proces Monitors
without any control function, or as Controllers with
Analog Outputs, Serial Data Ports and Set Point
Relay or Transistors.
CALIBRATION
The Quartz Time Base can be multiplied with a
scaling factor. The internal clock frequency will be
increased when the factor is positive, or decreased
when negative. The Calibrating Submenu can be
entered as follows:
Switch-off the instrument and switch-on again while
pressing the key MENU until the display shows
HtESt. Press the key MENU again, the display
shows e.g. - 5. This factor can be incremented at
the display with the key UP or decremented with
DOWN for positive or negative values. The positive
number increases, the negative value decreases the
clock frequency. After selection, switch-off the
instrument. When switched-on again, the display
returns into the selected display mode.
