It is recommended that all setup of the Apex2 controller be completed using
ESM. ESM provides a streamlined approach that can speed up the setup of
the Apex2 controller in comparison to setup via the controller user interface.
All setup parameters are accessed through the “Main Menu “of the Apex2
controller. The initial setup of the Apex2 controller is aided through the use
of the Apex2 Setup Wizard that will be initiated upon initial startup of the
controller.
a. Dishmachine Mode: The dishmachine mode can be set in the “Setup
System – Machine ” menu. The dishmachine setup will determine what
dispensing parameters are available in the “Adjust Dispensing” menu. The
dishmachine modes available are below. NOTE: Specific machine make
and model must be identified within the Location’s Service Item when
teaming the Apex2 controller in ESM. Configuring the dishmachine for
chemical sanitizing must also be done within the Service Item in ESM.
i. Door Machine – Probe Mode:
1. In Door Machines, the rinse is triggered by either the rinse signal
or the (optional) pressure switch. As the rinse is triggered, the rinse
delay (if any) begins. After the delay, the rinse pump runs at the set
rinse pump speed for the programmed Rinse Pump Limit or until the
rinse input is turned off, whichever comes first.
ii. Door Machine – Timed Mode:
1. Door machine functionality, such as rack counting and rinse
dispensing, are identical in both Probe and Timed mode. However,
Timed Mode does not have a wash tank monitoring function and the
detergent dispensing is different.
When an unqualified rinse signal (a rinse signal not proceeded by a
detergent signal) is received, the detergent is dispensed for the time
set in the Initial Detergent Charge. At each subsequent detergent
signal, the detergent is dispensed for the set Detergent Valve Run
Time, at the interval set in the Detergent Dose Interval.
iii. Conveyor Machine – Probe Mode:
1. Conveyor Machine, the rinse is triggered by either the rinse signal
or the (optional) pressure switch. The rinse pump is activated with a
qualified rinse signal and will run throughout the duration of the
signal.
iv. Conveyor Machine—Timed Mode:
v. Flight Machine – Probe Mode:
b. Product Selection: Apex2 detergent, rinse additive and third product
selections are found in “Setup System – Product Selection” menus.
Several controller conditions are dependent on the specific products
chosen therefore products chosen must accurately reflect products being
used with Apex2.
