1Visually inspect the transport packaging for signs of external damage
2Unpack the Vacuum Gauge Controller and put the packaging material aside
NOTE:
Keep the packaging material for later use. The Vacuum Gauge Controller must be stored and transported in the original packaging material only.
3Examine the Vacuum Gauge Controller for completeness
4Visually inspect the Vacuum Gauge Controller for signs of damage
WARNING
Damaged product.
Putting a damaged product into operation can be extremely dangerous.
Never attempt to put a damaged product into operation. Secure the damaged product from unintended operation. Send a damage report to the haulage company or the insurer.
The Vacuum Gauge Controller can be used as follows: As a desk-top unit, mounted in a control panel, or mounted in a 19" rack. In each of these cases you must pay attention to the following safety note:
CAUTION
Too high ambient temperature.
Exceeding the maximum permitted ambient temperature may damage the unit.
Make sure that the maximum permitted ambient temperature is not exceeded and that the air can flow freely through the louvers. Do not expose the unit to direct sunlight.
In order to use the Vacuum Gauge Controller as a desktop unit, proceed as follows:
1Turn the Vacuum Gauge Controller upside down as shown in Fig. 3-1, 10
2Push the supplied rubber strip onto the lower edge of the front panel
3Stick the supplied rubber feet to the bottom of the casing
Fig. 3-1 Using the product as a desk-top unit
4Turn the Vacuum Gauge Controller back to normal orientation and place it on the required location
In order to mount the unit in a control panel, the following cutout is required:

10 |
tinb07e1-e 2011-07 Vacuum Gauge Controller |
NOTE:
In order to reduce the strain on the front panel it is recommended to support the bottom of the unit.
The Vacuum Gauge Controller is designed for installation into a rack chassis adapter according to DIN 41 494 (19", 3 HE). For this purpose, 4 collar screws and 4 plastic sleeves are supplied with the unit.
WARNING
Lower protection class of the rack.
If the product is installed in a rack, it is likely to lower the protection class of the rack (protection from foreign bodies and water) e.g. according to the EN 60204-1 regulations for switching cabinets.
Take appropriate measures to restore the required protection class of the rack.
Fig. 3-3 Mounting the unit in a rack
NOTE:
In order to reduce the strain on the front panel it is recommended to equip the rack chassis adapter with a guide rail.
NOTE:
For safe and easy installation of heavy rack chassis adapters, it is recommended to equip the rack frame with slide rails.
1Fasten the rack chassis adapter in the rack
2Insert the Vacuum Gauge Controller into the rack chassis adapter
3Fasten the Vacuum Gauge Controller with the supplied collar screws and plastic sleeves to the rack chassis adapter

11 |
The mains connection (Fig. 3-4, 11, Pos. G) is designed for a mains cable which contains a European appliance connector on the device side.
A mains cable is supplied with the unit. If the plug is not compatible with your wall socket, you have to get a suitable mains cable:
•Three-conductor cable with protective ground
•Conductor cross-section 3 × 1.5 mm2 or larger
The ground screw (Fig. 3-4, 11, Pos. I) can be used to connect the Vacuum Gauge Controller with the protective ground of the pumping station.
1If required: Connect the protective ground of the pumping station with the ground screw. Use a protective conductor.
The SENSOR connection is used to connect the sensors.
For each channel, there are two connections available which are connected in parallel: An 8-pin RJ45 appliance socket and a 15-pin D-Sub appliance socket. See
Fig. 3-4, 11, Pos. A…C.
Pin assignment
Fig. 3-5 Three-conductor cable with protective ground (example)
WARNING
Mains power.
Improperly grounded devices can be extremely dangerous in the event of a fault.
Use three-wire mains or extension cables with protective ground only. Plug the mains cable into wall sockets with protective ground only.
WARNING
No mains fuse.
The Vacuum Gauge Controller is not equipped with a mains fuse.
The wall socket must be protected with a fuse (max. 10 A).
1Connect the European appliance connector of the mains cord with the mains connection of the unit
2Connect the plug of the mains cable with the wall socket
NOTE:
If the unit is installed in a switching cabinet, the mains power can be supplied via a switchable central power distributor.

CAUTION
Improper sensor.
Sensors which are not designed for use with the Vacuum Gauge Controller may damage the unit.
Operate the Vacuum Gauge Controller with proper sensors only. See Chapter 2.3.1 Sensor connections, 8.
CAUTION
Multiple connection.
Only one sensor may be connected to each of the channels. Otherwise the connected sensors will be damaged.
Never connect more than one sensor per channel.
Connecting
1Channel 1: Connect the sensor with to the CH1-A or CH1-B connection. Use a shielded 1:1 cable.
2Channel 2: Connect the sensor with to the CH2-A or CH2-B connection. Use a shielded 1:1 cable.
3Channel 3: Connect the sensor with to the CH3-A or CH3-B connection. Use a shielded 1:1 cable.
The switching functions and the error monitoring system influence the state of several relays inside of the Vacuum Gauge Controller. The RELAY connection (Fig. 3-4,
11, Pos. J) allows to utilize the relay contacts for switching purposes. The relay contacts are potential-free (floating).

The PARA button is used to select the parameter mode. The PARA indicator (Pos. B) is illuminated and you can modify various parameters. See Chapter 4.5 Parameter mode, 19.
Arrow buttons (DOWN/UP)
The arrow buttons are required for entering data in the parameter mode. Pressing one of these buttons will decrease or increase the currently displayed value. In the following, these buttons will be referred to as DOWN and UP, respectively.

1Switch the mains switch on. See Fig. 3-4, 11, Pos. H.
After switching on, the Vacuum Gauge Controller will perform the following actions:
•Self test
•Identify all sensors
•Restore the previously set parameters
•Activate measurement mode
•Adapt parameters (if a sensor type has changed meanwhile)
1Switch the mains switch off. See Fig. 3-4, 11, Pos. H.
CAUTION
Delay time.
After switching off, the Vacuum Gauge Controller requires approximately 10 seconds to initialize again.
Wait for at least 10 seconds before you switch the Vacuum Gauge Controller on again.
NOTE:
If the Vacuum Gauge Controller has been installed in a control panel or a rack, it can also be switched on and off via the central power distributor.
The Vacuum Gauge Controller can be set to one of the following operating modes:
Measurement mode
The measurement mode is the standard operating mode. It displays the pressure readings of the sensors. In case of an error, a status message is displayed instead. See Chapter 4.4 Measurement mode, 17.
Parameter mode
The parameter mode gives you access to various parameters. You can check the parameter settings or modify them using the arrow buttons. This allows you to configure the Vacuum Gauge Controller. See Chapter 4.5 Parameter mode, 19.
Program transfer mode
The program transfer mode is used to transfer the latest version of the firmware to the Vacuum Gauge Controller. See Chapter 7.2 Program transfer mode, 45.
16 |
tinb07e1-e 2011-07 Vacuum Gauge Controller |
The Vacuum Gauge Controller automatically selects the measurement mode after it has been switched on.
When the unit is set to the parameter mode, it will automatically return to the measurement mode if no button is pressed for 10 seconds.
The measurement mode is the standard operating mode. It displays the pressure readings of the sensors. A status message is displayed if the pressure exceeds the permissible range. See Tab. 4-1, 17.
