Inside the SERVICE MENU it is possible to:
• display and edit all the machine parameters;
• access the DATALOG, i.e. a file of events that occurred during machine operation (only for modular rack
type);
• display information of a general nature, such as the machine software versions;
• consult a file of statistics relevant to the various machine load activation times and starts (only for modular
rack type).
• adjust the rinse flowrate cock ( just for atmospheric rack type).
• Save the parameters, datalog content and content of the statistics in a removable
backup memory (for modular RT's only).
• Set the pressure sensors that detect the levels of the airgap, Duo rinse tank, wash tank and prewash tank.
After entering the SERVICE MENU switch the machine off and then on again to return to normal operation.
The various SERVICE MENU items can be selected by using the increase (“A” - (Figure 1)) and decrease
(“B” - (Figure 1)) keys.

(*) For the other equipment families, see par. Table 1 Machine codes list and relative programming

** The table given below indicates the delay between transit of the rack on the autorinse lever and stopping of
the rinse phase.
E.g. in a WTM165 working at high speed (165 racks/h) the rinse pump keeps operating for 11 seconds after
the last rack has released the autorinse lever.
*** Procedure for correctly setting the “Max. motor curr.” parameter:
1. Wait until the machine, complete with tables, is ready for a wash cycle.
2. Start a wash cycle and read the current absorbed by the gear motor
( refer to par. A1 “DISPLAY OF AUXILIARY VALUES”).
3. Add 2 to the read value (e.g. if “Motor current” = 34 ---> 34+2=36 decA).
4. Set the “Max. motor curr.” parameter with the value thus obtained.
The Rack Type leaves the factory with the “Max motor curr.” parameter already set to the optimum
value. Reset it only when replacing a PCB or the gear motor.

A4.2 DATALOG (ONLY FOR MODULAR RACK TYPE)
Accessing the "DATALOG" mode allows a number of events that occurred in the machine to be displayed.
In addition to the event, the screen also shows the time the event began and ended, as well as other information whose significance depends on the type of event recorded.
Every event is characterised by a START date and time and a STOP date and time.
The event STOP can be recorded when its cause is no longer present (e.g. a temperature exceeding the per-
missible upper limit and then coming within the correct range),
or when the machine is switched off following shutdown by the user (POWER OFF) or no power (POWER FAIL).
In the latter case, event STOP is described with the indication POWER OFF or POWER FAIL.
If accessing the display of an event that began after the last machine start and which has not ended because
its cause is still present, closing of the event is not displayed.
