Initial Set-up
User LEDs
During the initialisation process the User LEDs can be in one of the following
states
User LED State
Description
1
RED Flashing
2 second period
Unit initialising. If remains in this state, then unit does not a valid UCP1 fitted.
2
RED/AMBER Flashing
2 second period
UCP1 valid.
For units fitted with a display, the unit requires factory set-up (Number of Electrodes and
Number of Turns)
For units fitted with a configuration board, the UCP2 and/or UCP3 are not being detected.
3
RED/GREEN Flashing
2 second period
UCP1 valid.
For units fitted with a display, the unit requires site set-up.
This state does not occur if the unit is fitted with a configuration board.
4
User LED 1 -
RED/AMBER/GREEN
User LED 2 – OFF
Unit in configuration set-up mode, as instructed from the attached display node.
5
User LED 1 & LED 2 -
RED/AMBER/GREEN
Invalid configuration. The combination of UCP1 & UCP2 or UCP1 and the number of turns is
not valid.
Prior to the start of the initialisation process, the LEDs will flash Green, Red,
Amber repeatedly for 10 seconds to check that the LEDs are operation
correctly.
Remedy
:
1
Check that UCP1 is fitted to plug fitted to CR4 pins 7 & 8 for units with Alpha-numeric
display or fitted to configuration PCB part number 1150634, which is fitted to CR4 if no
display is fitted. See page 16 of manual for more details. Ensure that good electrical
contact is made in each case.
2
a) For units without a display, check that UCP2 is fitted to the configuration PCB (see page
16 of the “Installation, Operation & Maintenance Manual”) and that jumper J2 is set to
“electro boiler” and J1 is set for the correct site control signal.
b) For units with a display, select “factory set-up”, logon using password “2121” and enter the
number of power electrodes and number of times the electrode cable passes through the
current sensing transformer (this information can be found in section 1.5 of the manual
and drawing LZD557 sheet 3 of 3).
Please note that this will only be necessary if the PCB is
replaced as a new unit will be sent out with the factory set-up pre-installed.
3
For units with a display:
Enter “Set-up unit”, enter the “control signal” type and “site
voltage”, see Alpha-numeric display module operating manual..
4
For units with a display:
Once the unit has been “set-up” press ok at the prompt “Apply
changes are you sure *?*” when the unit will exit this state.
5
For units with an Alpha-numeric display:
Re-enter “Factory set-up” using password
“2121” and re-enter the correct “number of power electrodes” and “number of turns”
information, following the on screen prompts
For units without a display:
Check that UCP1 & UCP2 are securely fitted to the
configuration PCB.
