The ingress protection to EN 60529 against external inuences depends
on the basic instrument and is found in the respective data sheet.
The limit switches can be used in the range from -20 to +70 °C. Where
the permissible temperatures for the basic instrument (see data sheet)
deviate from this range, the lower values are valid.
For further specications see the corresponding WIKA data sheet and
the order documentation.

4. Design and function
4.1 Description
The built-in electrical switch contacts (reed contacts) are auxiliary
current switches which open or close (change-over contacts) connected
electric circuits at the set limits via the permanent magnet which is
moved by the instrument pointer. The reed contacts used are bistable
switches, which keep their condition after a signal change up to the next
actuation.
4.2 Scope of delivery
Cross-check the scope of delivery with the delivery note.
5. Transport, packaging and storage
5.1 Transport
Check instrument for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: In accordance with measuring instrument

6. Commissioning, operation
6. Commissioning, operation
6.1 Mechanical connection
In accordance with the general technical regulations for pressure
GB
gauges (e.g. EN 837-2 "Selection and installation recommendations for
pressure gauges").
When screwing gauges in, the force required for this must not be
applied through the case or the cable terminal box, but rather through
the spanner ats (using a suitable tool) provided for this purpose on the
square shaft of standard connections.
Installation with
open-ended spanner
Correct sealing of pressure gauge connections with parallel threads
must be made using suitable sealing rings, sealing washers or WIKA
prole seals. The sealing of tapered threads (e.g. NPT threads) is made
by providing the thread , with additional sealing material such as, for
example, PTFE tape (EN 837-2).
Spanner ats
Sealing face
Sealing in the
thread
The torque depends on the seal used. Connecting the gauge using
a clamp socket or a union nut is recommended, so that it is easier to
orientate the gauge correctly. When a blow-out device is tted to a
pressure gauge, it must be protected against being blocked by debris
and dirt.
WIKA operating instructions pressure gauge model PGS with reed contacts
10
14000322.01 03/2011 GB/D/F/E
6. Commissioning, operation
With safety pressure gauges (see dial symbol k) ensure that the free
space behind the blow-out back is at least 15 mm.
6.2 Special requirements for the installation point
If the line to the measuring instrument is not adequately stable, a measuring
instrument holder should be used for fastening (and possibly via a exible
capillary). If vibrations cannot be avoided by means of suitable instal-
lation, instruments with liquid lling should be used. The instruments
should be protected against coarse dirt and wide uctuations in ambient
temperature.
In rare cases an actuation of the reed switches can occur due to an
impermissibly high shock or vibration. In this case these reed switches
have to be reset after installation of the instrument in the measuring
point by moving the instrument pointer once over the set switch point
(reed switch).
6.3 Electrical connection
The electrical connection must only be made by qualied skilled personnel. Connection details and switching functions are given on the product
label. Connection terminals and earth terminal are appropriately marked.
The mains connection lines to be provided must be dimensioned for
maximum instrument power consumption and comply with IEC 227 or
IEC 245. For power ratings (see "Specifications") and protective circuits
with inductive and capacitive loads see chapter "7. Contact protection
measures".

6.4 Adjusting the set pointers
The setting of the set points is achieved using the adjustment lock in the
window with the aid of the adjustment key (part of the scope of delivery;
found in standard instruments on the side of the terminal box).
GB
With nominal size 160 measuring instruments it has to be ensured that
the adjusting arm is pushed down exclusively in the area of the set
pointer to be adjusted. Otherwise damage to the instrument pointer or a
misadjustment of the zero point cannot be excluded.
Set pointer
Adjustment lock
Adjusting arm
Removable
adjustment key
The set pointers of the limit switches are freely adjustable between 10 %
and 90 % of the scale range; the distance between the two set pointers
is approx. 10 % of the scale range (corresponds to approx. 30 ∢°).
Commissioning
During the commissioning process pressure surges must be avoided at
all costs. Open the shut-o valves slowly.
7. Contact protection measures
Mechanical contacts must not exceed the specied electrical values for
switching current and switching voltage independent of each other, not
even for a short time only.
For capacitive or inductive loads we recommend one of the following
protective circuits:

14000322.01 03/2011 GB/D/F/E
7. Contact protection measures
7.1. Inductive load with DC voltage
With DC voltage the contact protection can be achieved via a freewheeling diode, connected in parallel to the load. The polarity of the
diode must be arranged so that it closes when the operating voltag
e is on.
Example:

7.2. Inductive load with AC voltage
With AC voltage two protection measures are possible:

7.3. Capacitive load
With capacitive loads elevated switch-on currents arise. These can be
reduced by series-connecting resistors in the supply line.

8. Maintenance and cleaning / 9. Dismounting and disposal
8. Maintenance and cleaning
8.1 Maintenance
The instruments are maintenance-free. The indicator and switching
function should be checked once or twice every year. For this the
instrument must be disconnected from the process to check with a
pressure testing device.
Repairs must only be carried out by the manufacturer or appropriately
qualied skilled personnel.
8.2 Cleaning
CAUTION!
■
Clean the pressure gauge with a moist cloth.
■
Wash or clean the dismounted pressure gauge before
returning it, in order to protect sta and the environment
from exposure to residual media.
9. Dismounting and disposal
WARNING!
Residual media in dismounted pressure gauges can result
in a risk to persons, the environment and equipment. Take
sucient precautionary measures.
9.1 Dismounting
Only disconnect the pressure gauge once the system has been
depressurised!
When dismounting, close the compensating valve (if available).
GB
9.2 Disposal
Incorrect disposal can put the environment at risk. Dispose of instrument
components and packaging materials in an environmentally compatible
way and in accordance with the country-specic waste disposal
regulations.
