5. Setting the
High and Low Pressure Alarms in the "PRESS" Display
Mode:
Important Note: If your FP-5L is certified as a primary replacement
instrument for fuel pressure, the pressure alarm limits cannot be changed,
as they have been set at the factory. However, if you are using a non-
primary FP-5L, you have the flexibility to customize these limits.
In the “PRESS” Display Mode the following alarms may be set: Note - If
Fuel Pressure is a pimary function with limits, setting the limits in the field
is locked-out. The limits will be set by E.I.
High Pressure Alarm - A High Pressure Alarm may be programmed to
blink the H/L PRESS Warning LED when the displayed pressue value
exceeds your programmed high setpoint. Pushing any button or switch will stop the blinking but the H/L
Pressure Warning LED will stay on.
This limit is intended as a warning. It should be set to the highest
acceptable level for the function measured. In the “PRESS” Display
Mode a bar in the upper left corner of the display will be shown when the
high limit has been violated. Programming this limit to “000” disables the
alarm.
Low Pressure Alarm - A Low Pressure Alarm may be programmed to
blink the H/L PRESS Warning LED when the displayed Pressure value
exceeds your programmed low setpoint. Pushing any button or switch will
stop the blinking but the H/L Pressure Warning LED will stay on. This
limit is intended as a warning. It should be set to the lowest acceptable
level for the function measured. In the “PRESS” Display Mode a bar in
the lower left corner of the display will be shown when the low limit has
been violated. Programming this limit to “000” disables the alarm.
If the "PRESS" Display Mode is not going to be used, program the High and Low Pressure Alarms to "000".
This will cause the display to show "OFF" when the "AUX" Display Mode is selected.
To program the High and Low Pressure Alarms, perform the following steps:
A. Select the “PRESS” Display Mode.
