3 Installation
Skilled personnel
The unit may only be installed by personswho have suitable technical training and thenecessary experience or who have been in-structed by the end-user of the product.
The TPG 261 is suited for incorporation into a 19" rackor a control panel or for use as desk-top unit.
DANGER
Caution: damaged productPutting a damaged product into operation canbe extremely hazardous.In case of visible damages, make sure theproduct is not put into operation.
The TPG 261 is designed for installation into a 19" rackchassis adapter according to DIN 41 494. For this pur-pose, four collar screws and plastic sleeves are suppliedwith it.
DANGER
Caution: protection class of the rackIf the product is installed in a rack, it is likelyto lower the protection class of the rack(protection against foreign bodies and water)e.g. according to the EN 60204-1 regulationsfor switching cabinets.Take appropriate measures for the rack tomeet the specifications of the protectionclass.

In order to reduce the mechanical strain on the frontpanel of the TPG 261, preferably equip the rack chassisadapter with a guide rail.
For safe and easy installation of heavy rack chassisadapters, preferably equip the rack frame with slide rails.

Caution: protection class of the control panelIf the product is installed in a control panel, itis likely to lower the protection class of thecontrol panel (protection against foreignbodies and water) e.g. according to theEN 60204-1 regulations for switching cabi-nets.Take appropriate measures for the controlpanel to meet the specifications of the pro-tection class.
For mounting the TPG 261 into a control panel, the fol-lowing cut-out is required:

3.2.2 Installation in aControl Panel
18 BG 805 195 BE / B (2004-08) TPG261.oi
Slide the TPG 261 into the cut-out of the controlpanel …
… and secure it with four M3 or equivalent screws.
The TPG 261 is also suited for use as desk-top unit. Forthis purpose, two self-adhesive rubber feet as well as aslip-on rubber bar are supplied with it.
Stick the two supplied rubber feet to the rear partof the bottom plate …
… and slip the supplied rubber bar onto the bot-tom edge of the front panel.
3.2.3 Use as Desk-TopUnit
BG 805 195 BE / B (2004-08) TPG261.oi 19
Select a location where the admissible maxi-mum ambient temperature (→ 9) is not ex-ceeded (e.g. due to sun irradiation).
DANGER
Caution: line voltageIncorrectly grounded products can be ex-tremely hazardous in the event of a fault.Use only a 3-conductor power cable withprotective ground. The power connector mayonly be plugged into a socket with a protec-tive ground. The protection must not be nulli-fied by an extension cable without protectiveground.
The unit is supplied with a power cord. If the mains con-nector is not compatible with your system, use your own,suitable cable with protective ground (3×1.5 mm3).
The socket must befuse-protected with
10 Amax
If the unit is installed in a switching cabinet, the mainsvoltage should be supplied and turned on via a centraldistributor.

Make sure the TPG 261 is correctly installed and thespecifications in the Technical Data are met.
The power switch is on therear of the unit.Turn the TPG 261 on withthe power switch (or cen-trally, via a switched powerdistributor, if the unit is in-corporated in a rack).
After power on, the TPG 261 …• automatically performs a self-test• identifies the connected gauge• activates the parameters that were in effect before
the last power off• switches to the Measurement mode• adapts the parameters if required (if another gauge
was previously connected).
Turn the TPG 261 off with the power switch (or centrally,via a switched power distributor, if the unit is incorpo-rated in a rack).
Wait at least 10 s before turning the TPG 261on again in order for it to correctly initialize it-self.

The minimum hysteresis between the upperand lower switching threshold is at least 10% ofthe lower threshold or 1% of the set full scalevalue. If the value of the minimum hysteresisdrops below these values, the upper thresholdis automatically adjusted to a minimum hystere-sis. This prevents unstable states.

The upper switching threshold(Setpoint high) defines the pres-sure at which the switching func-tion is deactivated when the pres-sure is rising.

5 Communication (Serial Interface)
The serial interface is used for communication betweenthe TPG 26x 1) and a computer. A terminal can be con-nected for test purposes.When the TPG 26x is put into operation, it starts trans-mitting measured values in intervals of 1 s. As soon asthe first character is transferred to the TPG 26x, theautomatic transmission of measured values stops. Afterthe necessary inquiries or parameter modifications havebeen made, the transmission of measured values can bestarted again with the COM command (→ 71).
Pin assignment of the 9-pole D-Sub connector andRS232 interface cable → 23.
The data transmission is bi-directional, i.e. data andcontrol commands can be transmitted in either direction.

6 Maintenance
The product requires no maintenance.
For cleaning the outside of the TPG 261, a slightly moistcloth will usually do. Do not use any aggressive orscouring cleaning agents.
DANGER
Caution: mains voltageContact with live parts is extremely hazardouswhen liquids penetrate into the unit.Make sure no liquids penetrate into theequipment.

If your TPG 261 firmware needs updating, e.g. forimplementing a new gauge type, please contactyour local Pfeiffer Vacuum service center.
Most of the settings you may have defined in the Pa-rameter and Test mode will not be affected by a firm-ware update. To be sure, note your parameter settingsbefore upgrading the firmware (→ 94).
Turn the TPG 261 off.
Connect the TPG 261 with the serial COM1(COM2) interface of your PC via a 9-pole D-Subextension cable (→ 23) (the firmware of theTPG 261 cannot be loaded from a Mac).
With a pin (ø<2 mm), depress the switch on thetop of the unit, under the housing, and turn theTPG 261 on.
After power on, the display remains dark.

Unpack the self extracting file.
If you have not connected the TPG 261 to theCOM1 interface:
• Open the batch file …
• … edit the interface …
• … and save the new setting.

If the program transfer was successful, quit the Updatemode by turning the TPG 261 off.
Wait at least 10 s before turning the TPG 261on again in order for it to correctly initialize it-self.
The TPG 261 is now ready for operation. To besure, check that the current parameter settings areidentical with the previously defined settings(→ 94).
