EVLJBOX HP Sequencer -
Application manual
Main page
Viewing of the “main page” changes according to machine
status:
– If the sequencer is on “OFF by key” or “OFF by alarm”
– If the system is off or on
If a fault occurs in the control probe, the sequencer will go
into the “OFF by alarm” state.
The control probe alarm, AL13 if the probe is that of the
evaporator or AL15 if the probe is that of the condenser,
has manual reset. Once the fault has been fixed and the
alarm reset, the sequencer will automatically return to the
condition prior to the alarm.
If the sequencer is on “OFF by key” or “OFF by alarm”,
MODBUS communication with the slaves is disabled. After
5 minutes, they will begin working autonomously and
independently.
When the “ON/STAND-BY” key is pressed for 2 seconds,
MODBUS communication with the slaves will begin.
The “system off page” will be displayed on the sequencer
with the following information:
– Active alarms in the master and relative number
– = no alarm active
– = at least one alarm active
– Current date and time
– Software version
– Command to switch on the sequencer system
To prevent the sequencer being accidentally switched on,
which could cause problems with the sensitive MODBUS
communication, press the “DOWN”
key before switching it
on. The message “SYSTEM START-UP” will appear, press the
“ENTER”
key to confirm.
Users can browse the machine status pages from this page
using the “LEFT”
and “RIGHT” keys:
– Master
– Slave
By holding down the “ON/STAND-BY” key for 2 seconds
on this page only, it is possible to disable MODBUS
communication with the slaves.
Machine status will therefore be in “OFF by key”.
If the sequencer is started up and MODBUS communication
with all the slaves has not yet been established, the word
“Initialisation” will flash underneath.
Once communication has been established, the sequencer’s
ON page will automatically be loaded.
