INTRODUCTION
The Zenyth 2.5 Automation allows the operator to roast manually and save roasting profiles
for duplication in auto mode. It isdesigned to give the operator predictable consistency and
the ability to accurately repeat roast profiles.
This manual is NOT intended to teach how to roast. It is intended to explain the features
and the functions of the roast system buttons only.
The roast system uses a touch screen to control the roasting system. Buttons are
activated with slight pressure (finger or plastic stylus) directly on the screen.
To achieve the most versatility with Zenyth 2.5 Automation, please read the entire
manual before operating the equipment.
A UPS (battery backup) system is recommended.
Please review all safety and installation requirements listed in the appropriate roaster
operation manual.
Operators must understand how to start and stop the motors using the control system. In
particular, the operator should be aware of the emergency stop button on the control
panel. This button disconnects the outputs of the PLC which will end all functions of the
roaster.
Screen calibration can be accessed upon cycling power to the screen. On powerup, a
calibration screen will be displayed. After 10 seconds of inactivity, the screen with boot
up to the Main Screen.

CR Series Roaster System Screen
The hour meter is located on this screen and shows the number of hours the roaster has
been in operation. This timer can be used to schedule cleaning/maintenance. On the
setup screen, the hour meter can be reset.
The 8-hour, 40-hour, & Semi-annual lamps will light up when those maintenance
intervals are due. There is a built-in maintenance schedule based on roasting time for
the 8 hour and 40-hour cleanings. The Semi-annual is based on every 6 months. Refer
to the “Maintenance Manual”, which covers the 8-hour, 40-hour, & Semi-annual
cleanings.
The “MENU”, “SET-UP” screen, and “DATA LOGS” screen can be viewed by pressing
the buttons along the bottom.
Click on the arrow at the top left of the screen for the pop-out menu to access the below
system functions. Here the roaster system or individual motors/functions can be started.
If equipped, the buttons for a loader will appear on this screen if the option is enabled on
the “SET-UP” screen. Other options work the same.

Press the green START STOP SYSTEM button to shut the roaster off. This button turns
off the gas immediately; however, the drum and roast air blower will continue to run until
the roaster temperature drops below 250°F (121°C). A yellow pop-up will appear and
indicate “Roaster is in Automatic Cool-down Mode” if that is the case. The temperature
where the roaster will stop can be adjusted in the Setup screen with the COOLDOWN SET
POINT for the CR-only. Please note that if the bean temperature probe has registered
temperatures above the allowed high-limit (475°F / 252°C) then the operator is in full
control and cool-down is not automatically initiated! Also, an E-Stop reset after E-Stop
will always bring the roaster into a state where it is fully controllable by the operator.
HIGH LIMIT RESET
If the roaster temperature rises above 485°F (246°C) a safety mechanism will shut down
the gas flow to the burners. Once the temperature drops back down to normal operating
range the HI LIM RESET button must be pressed in order to reignite the gas system. (On
some roasters another reset is performed with a physical manual reset button).
HOPPER LOADED RESET (CR only)
Selecting this button will override the interlock and warning that the green-bean-hopper is
already loaded, allowing the operator to run the loader again. After the loader has run for 20
seconds or more (OR if the hopper has a green-bean-sensor mounted in the hopper) the
hopper is considered to have green beans present and additional loading is prohibited. Any
time the hopper gate is opened the warning is also reset.

CROPSTER REPLAY
The values for logging within Cropster are always available, whether the option is on or off.
Values are provided over Ethernet IP with direct access to the PLC. Fuel and Air values will
be available. To use the feature in Cropster to Replay profiles, the option first needs to be
selected. The option is on the Setup Screen and is called Cropster Replay. This option can
only be turned on when the roaster is in Manual mode (Auto mode will reset the option).
Once turned on, it will be indicated on the manual screen that it is turned on.
Z2.5 Automated roasters will need additional hardware, an Ethernet switch with a minimum
of three (3) ports, to allow another device to access data. It is to be noted that a roast must
be ended on the roaster HMI with the "End Roast" button, or by setting the end temperature
and activating the use of the End Temperature. Please refer to Cropster directly on how to
set up and use this option. Cropster ™ is a trademarked name, visit the company’s website
at www.Cropster.com.
SEMIAUTO –USE PROFILE VIEW (CR-Only)
When this feature is turned on, the same fuel values that are in the loaded profile will be
used in the auto roast. The automation will not change any fuel values as long as the boxes
with a “-“ & “+” are set to zero (0). If the values in the boxes are other than zero (0) the
automation is allowed to modulate slightly around the saved fuel value to bring the bean-
temperature closer to the loaded profile. A value in the boxes of 1+ and 6- will allow the
automation to use 31% or 24% fuel for a 30% fuel value in the profile pending if the actual
bean-temperature is behind or ahead of the profile. The fuel values will be used by time or
by temperature pending the setting of the “AUTO ROAST BY TEMP” button.
COOLDOWN SET POINT (CR-Only)
This is the temperature where the roaster will shut-down when in cool-down-mode.
