TO BY-PASS THE 3'/60' STAND BY TIME, SYMPLY JUMP "TEST" CONTACTS WITH PCB ENERGIZED
G. JUMPERS
The Flaker PC Board is equipped by three jumpers:
J1
PURGE Used on machine equipped with Water
Purge Valve to purge out the water
from the water system every 12 hours
and when the machine restart from the
Bin Full
JUMP IN - Purge activated
JUMP OUT - Purge disactivated
PWD Used to Pump Out the water by means
of the Progressive Water Pump
supplied as a kit
JUMP IN - No Progressive Water Pump
installed/in operation
JUMP OUT - Progressive Water Pump
installed/in operation
3'/60' Delay time at start up
JUMP IN - 3 minutes delay
JUMP OUT - 60 minutes delay
J2
TEST Factory use ONLY
6/12 M Cleaning remind for the water system -
Red Light blinks/flashes with machine
ON
JUMP IN - 12 months set up
JUMP OUT - 6 months set up
60/70°C Set up of the Safety Condensing
Temperature Sensor
JUMP IN - 70°C
JUMP OUT - 60°C
H. EXTERNAL SWITCHES SOCKET
Connected to the external Green Master and
Red Alarm Reset Switches, it receives power
from the Master Switch as well as it provides
power to the Red Alarm switch in order to signal
any possible uncorrect operation condition of the
machine as clogged air filter (air cooled version
only) or short/missing of condensing water (water
cooled version) as detailed at item B.
It signal also the time for the cleaning of the water
system of the machine, cleaning that can be
change, according to the local water conditions,
from six month (standard - Jump In) to twelve
months (Jump Out).
Once cleaned the water system, it's necessary to
cancel the time stored into the PC Board by
pushing and hold for more then 5" the Red Alarm
Re-Set Button till it stops to blink.
I. FLOAT RESERVOIR
The float reservoir consists of a plastic water pan
on which is fitted a float valve with its setting
screw. The float valve modulate the incoming
water flow to maintain a constant water level in
the reservoir, level that corresponds to the one in
the freezing cylinder to ensure proper ice formation
and fluidity.
On the inner side of the reservoir cover are fitted
the two water level sensors which detects the
presence or the shortage of water in the reservoir.
