This key is used to move the blinking cursor to the next field right.
This key is used to move the blinking cursor to the next field up.
This key is used to move the blinking cursor to the next field down.
This key is used to select the current field in order to change values or control
parameters. Once a new value has been typed, press the key again to enter.
Control parameter options are toggled by repeatedly pressing the key. This key is
also used to clear a fault or shutdown status. If the fault condition is still present,
the fault indication will immediately return.
Hand-Held Terminal Control Screens
1.) On system power-up, the red power
indicator light on the GECO circuit board will
illuminate and the hand-held terminal will
boot up with the title screen. The model
number for the control software, along with
the revision and revision date, will be
displayed.
2.) If fault codes need to be cleared quickly to
resume normal operation, all alarm and
shutdown codes can be cleared from this
screen. However, for maintenance, and
documentation, the individual codes should
be reviewed and recorded first. If the cause
for any fault has not been fixed, the fault will
reactivate immediately. Press the ENTER
key when a CLR field is blinking to clear all
faults. Individual faults can be cleared one at
a time on other screens as well.
3.) A fault on the thermocouple screen
indicates that an overtemperature condition
has occurred on one of the catalyst
temperature sensors. The limit values may
be changed. Highlight any fault (Hi) field and
press the ENTER key to clear. An open
thermocouple connection will also cause a Hi
fault. Any other fault condition configured for
shutdown will be indicated by Control:SD.
