1 SAFETY AND CONFORMITY

1.1 Safety Instructions

The GEA Omni™ is reliable in operation if used as specified.
Hint!
Read the safety instructions in the GEA Omni™ operating manual before startup.
The intended use includes the observance and compliance of
all notices regarding hazard to persons and damage to property in the operating instructions,
the country-specific standards and safety regulations,
the instruction for installation, operation and maintenance,
the details of certificates,
the requirements for personnel,
Safety and Conformity
Safety Instructions
the obligation to exercise due care.
Only compliance with all provisions and guidelines will enable optimum protection of the personnel as well as dangers to the environment and the safe and smooth operation of the GEA Omni™.
Warning!
GEA Omni™ can cause hazard in case of improper or unintended use. A malfunction indica­tion on the touch screen cannot be ignored.
A personal injury or damage to the machine or plant can be the result.
For precautions to prevent danger see safety instructions in the operating manual.
Warning of electric shock!
Danger of electric shock exists.
More than one switch-disconnect may be necessary to isolate all electrical components.
Before maintenance work on the control panel, make sure that all electrical components are switched off.
Danger!
It should be ensured at any time that all are necessary processes for compressor cooling and lubrication in operation as long as the compressor is in operation.
This applies esprecially for the case where the compressor is unintentionally in operation. The unintentionally compressor operation can be determined by observation of the compressor motor feedback, the motor current or the motor speed.

Safety and Conformity Safety note concerning the connection of the GEA Omni™ with the starter panel
Instruction Manual | GEA Omni™
Control panel
Hint!
To minimize the possibility of interference from electromagnetic signals in the operation of the ICTD temperature converters, the following wiring guidelines must be observed:
The signal cables should be two conductor shielded cable. Twisted pair cable is preferable.
The signal cables should be run in conduits which do not contain any AC wiring.
The signal cables should not be run in parallel or in close proximity to VFD power cables.
All VFD equipment in the facility must be solidly grounded.
If the ICTD sensors are not mounted on the skid or compressor package, the convertor should be mounted at the probe location.
Operation of some high-powered radio or microwave communications equipment in close proxim­ity to the ICTD temperature converters, ICTD sensors, or interconnecting wiring may result in inaccurate readings for the associated temperature(s).

1.2 Safety note concerning the connection of the GEA Omni™ with the starter panel

Hint!
It is not permitted to add an external controller between the GEA Omni™ and the power panel; this would compromise the safety interlocks designed for protecting personnel and equip­ment. All control signals between the GEA Omni™ and the starter panel must be processed directly and must not flow indirectly via an external controller. GEA Refrigeration North Amer­ica, Inc. cannot otherwise guarantee the safe operation of the system.

2.7 Evaporator

Evaporator control is based on temperature. The evaporator temperature controls the operation of the zone based on its set point and related parameters.
A reset delay prevents all solenoids in the system from turning on at the same time. Any time the control panel is powered-up, reset, or after a shutdown condition, all evaporator zones will be placed into a reset delay condition. The first zone placed into operation is given a five second reset delay, and each subsequent zone that is ena­bled and not currently in a shutdown will be assigned a reset delay equal to the previous zone’s delay plus five seconds. This allows the evaporator zones to come out of reset delay in any order. A zone that is in reset delay will be represented by a dark green tile on the overview screen, and will display the remaining time until it will be permitted to start.
The defrost cycle for an Evaporator zone may be initiated in one of three ways:
46 GEA Refrigeration North America, Inc. | E_806550_2 | Generated 12.01.2016
Instruction Manual | GEA Omni™ Control panel
A manual initiate triggered through either the touch screen or communications.
An automatic defrost based on the run time of the zone’s liquid solenoid.
A daily defrost based on the current time of day.
User interface
Evaporator
With any of the modes of defrosting, the zone is placed into defrost immediately if no other zone on the same group is defrosting. If another zone on the same group is in defrost, the zone will instead be placed into pending defrost until the zone currently defrosting has completed the cycle.
The defrosting cycle may contain up to twelve stages. The amount of time the zone will remain in each stage is user adjustable.

fig.73: I/O Status tab display
This tab is used to display the current layout of the I/O system. Additionally, output slices may be forced to spe­cific values, but this functionality may only be accessed by a user with service level or higher permissions.
The current status of the I/O system may be viewed through the LED indicators shown in the upper portions of each slice. Slices that do not transmit or receive I/O signals, such as power and end slices are grayed out in the display. Any other slice may be clicked to display a detailed view like the ones shown below.
The scopes shown on the outer edges of all the displays illustrate the raw signal received or transmitted by each point.
Warning!
Caution should be exercised when forcing the value of outputs within the I/O status tab. Forc­ing a module to an improper value may cause harm to personnel or damage to equipment. If in doubt, contact trained personnel.
Hint!
If outputs are forced, the module will return to its original value after a thirty minute interval.

1. Create New User
The fields on the far right of the screen may be used to enter information for a new user. Each user will be given a unique User Name and may be assigned a unique Email Address and Password. The access level selected will be either Service or Operator. Admin access level may not be created. If the user level is set to Operator, three additional fields will be displayed which are used to select to what degree the user may control the system. Service users automatically have full access to all three of these options, so these fields will not display if the access level is set to Service.
Start/ Stop Access
This field contains a drop down list which is used to select whether the user has permission to start or stop the compressor. It may be set to No Access, Stop Access, Start and Stop or Start and Stop with Capacity Control Access. The default option is Start and Stop with Capacity Control Access.
Set Point Access
This field contains a switch which is used to toggle whether or not the user is permitted to access or change the control set points of the panel. By default, this option is set to true.
Clear Motor Start Timers
This field contains a switch which is used to toggle whether or not the user is permitted to reset the built in delay timers before the motor starts. By default, this option is set to false. Touching the Save User button below the fields will create a user using the information in the fields and add it to the table of current users.

2. Current Users
This section contains a table displaying all users that may log in to the panel. By default, there are two users: Service and Operator, though any custom users added in the manner described above will be dis­played in the table as well. The table contains three columns; the leftmost containing the name of the user, the middle containing the access level and the rightmost containing a checkbox which is used to select a user to be edited or removed. The rows corresponding to the two default users do not contain the checkbox in the leftmost column because they may not be modified or removed. When the checkbox corresponding to a user is selected, the fields used to create a user will automatically be filled in with the corresponding information. This will also enable the Save User and Delete User buttons. Any changes made to a custom user may be confirmed by touching the Save User button. Touching the Delete User button will remove the selected user from the table entirely. Only custom users may be deleted or have their access level modified.
3. User Timeout
This section is used to select whether the panel will automatically log a user out after a period of inactiv­ity. User timeout is not set by default, and must be enabled with the Timeout Enabled switch shown to the right of the screen. Toggling the switch on will enable the field shown below it.
User Access Timeout
This field contains a drop down list which is used to select the amount of time the panel must remain idle before the current user is logged out.

2.15.3 Network Tab

Instruction Manual | GEA Omni™
Control panel
fig.100: Network tab display
This tab is used to display the status of the panel’s network connections. It also allows the user to modify certain settings. These options may only be modified by a user with service level or higher permissions.
1.
Customer Network
This section displays the current network connection, if applicable. The switch displayed in this section is used to select whether DHCP, Dynamic Host Configuration Protocol, is enabled. If DHCP is enabled, the panel will automatically search for a network connection and will fill in the IP Address, Subnet Mask, Gate- way and DNS Server fields without user input. If DCHP is disabled, the values in these fields must be entered manually. If the panel successfully connects to the chosen network, the title of this section will dis­play Customer Network – Connected. Otherwise, it will display Customer Network – Disconnected.
Hint!
The IP Address Range 192.168.254.0 through 192.168.254.255 is reserved for the I/O Ethernet network Setup. To ensure the functionality of both networks, do not use this range for the cus­tomer LAN Connection.
2.
I/O Network
This section is used to display the IP Address and MAC Address of the panel’s I/O network coupler, if appli­cable. These values may not be modified and are only visible for users with access level of Service or higher. If the panel successfully connects to an appropriate network location, the title of this section will dis­play I/O Network – Connected. Otherwise, it will display I/O Network – Disconnected.
3.
VNC Server Settings
This section is used to select whether a user may remotely log into the panel using VNC and whether a password is required to do so. This section contains two switches. The switch on the left toggles whether VNC client access is enabled for the panel and the switch on the right toggles whether a password is required. If a password is required, it may be changed by typing a new password into the Password and Confirm Password fields and touching the Change Password button below.
