6.2.1 Change Date
Factory set, however, this parameter allows the
user to set the current date.
6.2.2
Change Time
Factory set, however, this parameter allows the
user to set the current time.
6.2.3
Weekly Timer
This function allows the user to set the controller to
automatically start and stop the engine once per
week. Select the day and time (24-hour clock) for
the engine to run. Once selected, choose the run
time desired, in minutes.
The engine will now
start once per week as programmed. The engine
will run for a minimum of 30 minutes or for the
duration of the RPT setting, whichever is
greater.
You can view the status of the Weekly Test date by
depressing the TIME/PRINT button twice.
6.2.4
Run Period Timer
To activate the RPT, the STOP MODE function
must be ‘Set for Automatic’ (see below in this
section). When the engine is started in response to
the pressure switch, it will continue to run for the
duration of the RPT, in minutes. Once timed out, if
no further starting causes prevail, the engine will
automatically stop.
If the engine is started manually the RPT has no
affect and the engine must be stopped manually.
If the STOP MODE function is ‘Set for Manual’,
the RPT does not affect the operation of the
controller and becomes inoperative.
The timing range for the RPT is: 1-60 mins
6.2.5
Language
The language can be selected for either English,
Spanish or French.
6.2.6
Pressure Transmitter
When selected as YES, the controller will start
based on the signal from the pressure transmitter.
When selected as NO, the engine will start when
the controller detects a contact closure between
terminals 31+11.
For both starting conditions above, the Sequential
Start Timer is activated when selected.
6.2.7
Pressure Start Point
The value programmed determines at what
pressure the controller will initiate a start command
to the engine.
The pressure range is:
1-500 PSI
Factory default:
1 PSI
6.2.8
Pressure Stop Point
The value programmed determines at what
pressure the system must reach before the
controller will STOP the engine, either manually
via the STOP pushbutton or automatically via the
RPT timer. If the actual pressure does not exceed
the STOP pressure value, the engine will continue
to run.
The pressure range is:
1-500 PSI
Factory default:
100 PSI
6.2.9
Low Suction Shutdown
This function monitors a contact closure between
terminals 29+11. If shutdown is disabled, the LCD
display will show low suction and the engine will
continue to run.
If shutdown is enabled, to prevent the controller
from responding to momentary hydraulic transient
pressure loss (which would otherwise shut down
the engine unnecessarily), a time delay must be
programmed to ensure a steady state.
The shutdown time delay is selectable between 0 -
30 seconds. Upon detecting a steady state contact
closure, the engine will turn off.
The reset mode of the engine is user selectable. For
AUTOMATIC reset, a time delay between 0 - 30
seconds is selected, after which the controller
observes the input for a true signal, and if true, will
not allow the engine to restart. If false, the
controller will function as normal and respond to a
start signal.
If MANUAL reset is selected, the RESET
pushbutton must be depressed to reset the
controller. If the situation continues to exist, the
controller will not restart the engine and the alarm
will reappear.
The LCD display will indicate ‘Low Suction
Shutdown’ in both situations.
NOTE:
that the RPT timer must be reset to thirty (30)
minutes when the controller is placed in service.
NOTE:
NFPA 20, Section 2-9.9, specifically prohibits the
installation of any device in the suction piping that
will restrict starting or stopping of the fire pump.
Eaton Corporation assumes no liability when this
function is used.
