4.4.2
It is recommended to connect the valve with a homogenous conduit. Connection on the “M”
conduit should be made as solid as possible, providing good contact on connections with
the use of tight (IP44) clamp block - PZ1 on Fig. 2.2.
4.5
Connect external auxiliary device, e.g. automatics control, external buzzer S-3, warning lamp LD-
2 (YTKSY 2 x 0.5 conduits), etc. In case of positioning optical and acoustic signalling devices in
the same location, it is recommended to use an integrated acoustic-optical signalling device of
SL-21 of SL-31 type. Having separated functions of buzzer and lamp, it can be connected to
MDP with a three-conductor conduit (YTKSY 2x2x0.5 recommended). Labelling of outputs and
their features were described in Table 2.1.
4.5.1
When it is necessary to connect a larger number of conduits (after using all factory gland
ducts), additional ducts (with diameter adjusted to conduits used) need to be installed on
the removable cover of the terminal chamber. Only correct ducts (IP54 or better) should be
used to maintain the proper level of unit’s tightness. Walls and bottom of the unit must not
be perforated! Conduits cannot be inserted directly to the unit by the drilled holes (without
gland ducts) or through the seal of the terminal clamp.
4.6
For MDP-4(8,16) connect ~230 power supply cable “B”.
The unit has an internal, unipolar power
switch. Maintain the proper sequence of 230V~ connection’s conduits: neutral to “N” (01), phase
to terminal “L” (02), PE ground cable to terminal (03). Certainty of power supply and no
interferences is a basic requirement for system efficiency and therefore conduit “B” should be
connected through the isolated fuse in the switchboard. Strong overvoltage in the ~230V supply
circuit can be the cause of damage of internal main supply fuse or cause interferences in
operation of the MDP unit.
For the MDP version: connect the 12V= supply cable “E” from the PS-3 power supply unit
(MDP-4(8)..A) or PS-6 (MDP-16…A) with the battery connected, maintain proper polarization (the
unit is protected by inverted polarization), (“+” to terminal “02”, “-” to terminal 01).

5. INITIAL CONFIGURATION MDP
NOTE:
all described procedures and messages of the LCD screen concern the standard version of the
unit. Possible descriptions of non-standard versions, modifications and revisions may be found in
attached appendix to the instruction manual (if any).
NOTE:
Press the keys gently not to damage mounting plates and internal circuits of the MDP.
5.1
The next stage of
System
activation is to configure the unit according to individual needs of
the Customer. It is conducted by means of the keyboard located in the front panel of the unit accessible
after opening of the transparent cover of the housing.
5.2
Switch on the power supply with the unit’s main switch. After power is turned on a test of signalling lights is
performed. The lights of Alarm2, Alarm1, Power supply, Failure are turned on and off in sequence. Then the
logo of Gazex company will appear on the LCD. The logo is displayed for 5 sec.
At this time initialization of unit’s settings takes place.
5.3
The next stage (
optional, for selected models
) is the stage of temporary deactivation of the
unit’s blocking. If the blocking is active, the dialog box presented below will be visible on the
screen. The date shown in the box specifies the date,
after which
the unit will be blocked. By
this time the unit is fully functional.
After conditions forcing the blocking are fulfilled,
contact service employees of GAZEX (by phone
under +48 22 6442511 or via the contact form
available at www.gazex.pl or by mail:
[email protected]), who will provide you with the
code for deactivation of temporary blocking of the
unit.
