16 T405S Indicator Service Manual
2 Introduction
2.2 Powering up the T405S
The indicator is always active as long as power is received. Power can be supplied by:
l
AC power cord connected to a properly grounded outlet (100 VAC - 240 VAC,
50 or 60 Hz)
l
External 12VDC @ 1.2 Amps up to 36VDC @400mA (14.4 Watts). These are
the power requirements for a fully loaded unit (16 x 350 load cell, 500mA out
the 5V COM port terminal block, 500mA load on USB Host, and Wireless
option card installed).
l
AC to 24VDC power converter (optional accessory for panel mount version)
2.3 Using the alphanumeric keypad
Use the alphanumeric keypad to enter numbers and words when prompted by the
indicator. For alphanumeric menu entries the graphics display will only show the last
six characters entered.
The action is similar to using a cell phone to select the number or letter. A rapid
succession of presses will scroll through the number on the key and then the letters,
starting with upper case and then lower case. The decimal key scrolls through the
negative sign, pound sign, colon, comma and percent sign. The
0 key toggles between
0 and a space.
2.4 Entering negative numbers or decimal point
To enter a minus sign for a negative number or a decimal point (or comma), press the
C key (or PRINT key) to clear the current value from the display.
Then to enter a negative number, with a single 0 displayed press SELECT . The first
character will then change to a (-) negative sign. Enter the rest of the digits normally.
To enter a decimal point (or comma), on a T405S use the decimal point key.
2.5 String index/character data entry
Below are guidelines to create or edit text and scale information for print formats. This
is a sample of a string entry display.

character.
