c. On the Relay there are dipswitches very similar to the timer in our 7700-7900 pumps.
d. From the factory the dipswitches 7 and 9 will be on. To turn the dipswitches ON the
dipswitch needs to be pressed down to the number side opposite of the open side.
Switch #6 = 5 seconds
#7 = 10 seconds
#8
= 20 seconds
#9 = 40 seconds
Example: If you turn #7 and #9 on, the time delay will be 10 plus 40 or 50 seconds.
C. Kettle High Limit Temperature Control
a. The kettle high temperature control system is completely redundant system to the
digital temperature control. The High limit control controls a second relay which is
wired in series with the relay controlled by the digital temperature control.
b. Cretors “CE” marked machines have been supplied with high limits since 1990 to
comply with the European Directives these high limits
were not resetting. Once they
trip, they must be replaced. Beginning July 2008, the CE marked machines began using
the same high limit used in non CE marked machines (cpn14593). These high limits
will reset when the temperature falls below their set point. In order to comply with the
CE directive a latching relay (cpn 14942) has been added to the control circuit. If the
high limit opens the relay will keep the kettle power off until it is reset. The relay is
reset by turning off the power to the machine. This is done by turning the rotary switch
off and back on or powering the unit off at the main breaker.
CAUTION: If high limit continually trips, check for a problem with the kettle
temperature control, temperature setting of the temperature control or the timer
setting of the sweet/salt timer
c. Beginning in May of 2006 UL requires that all cooking machines have auto-resetting
thermostats. Cretors and Company has started implementing auto-resetting high limits
into our repair kettle assemblies as well. Again, the end customer/user will not see any
difference in the operation of their machine but there is now an added level of safety so
that the kettle temperature will not be able to exceed a safe level, even if the normal
operating thermostat or temperature controller is adjusted to an unsafe level. This high
limit is preset and is NOT to be adjusted for any reason.
Tampering with the high limit
will void all warrantees. New wiring diagrams will be sent out with the new kettle
assemblies for reference.
