Introduction

Prosense S-DP32 Control Panel is able to provide automatic gas concentration reading and

protection against gas explosions. S-DP32 permanently transmits the gas concentration

measurement from detectors to the control unit. Before the gas concentration in the

atmosphere reaches the L.E.L., the control panel is able to shut off a gas valve, cut off power

and turn on an alarm via activating relays when correctly integrated to related control

devices. Prosense S-DP32 Control panel can manage up to 32 explosive-flammable and toxic

gas detectors as well as oxygen detectors with serial loop connection.

Prosense S-DP32 Control panel has two levels of alarm which are adjustable according to the

measuring range and one fault alarm for the detection loop. Individual relays per function

ensure remote controlled output. There are 4 relays on the panel. Two of them used as

alarm relays and configured as ALARM-1 and ALARM-2. There is one FAULT relay and one

AUX relay. The AUX relay can be defined as ALARM-1, ALARM-2 or ALARM-3. ALARM-3 is not

a level based alarm but it is an alarm driven by digital input connected to another external

device.

S-DP32 has 128x64 LCD screen on the front panel to show status of each detector. This LCD

screen and menu keys allow user to set correct properties for each detector like gas

concentrations by gas type, measurement unit, and range and alarm levels.

S-DP32 Gas Control Panel complies to IEC 60079-0:2017 and IEC 60079-29-1:2016 standard

requirements. Please refer to the certification label on the control panel to identify the type

of certification that relates to the product supplied.

Installation

The S-DP32 control panel box should never be placed in an explosive atmosphere and should

be readily accessible. It is necessary to drill holes for cable glands either on the top or

bottom of the control unit, depending on which side the electric cables are running in.

Please unscrew and remove the electronic parts before drilling to avoid any accidentally

damaging. S-DP32 control panel should not be placed nearby high voltage cables or power

cable, coaxial cables or transmitters, welding stations or frequency regulators. The S-DP32

panel box produced based on IP66 standard specifications. Always use prepared screw holes

to mount it and do not pierce panel from any other side. Always use suitable cable glands to

make cable entries.

There is a front plastic cover to protect panel from outer shells, water and dust. To reach to

panel first you need to open plastic cover via pressing both sides of the latches on the front.

If panel ordered with keys a key needed to open plastic cover.

If panel ordered with keys a key needed to open plastic cover.

Diagram 4: Front cover with key

In order to make panel connection, you need to open the front cover using the key at right

bottom side of front panel. The key works clockwise and vice versa.

Diagram 5: Locker.

S-DP32 panel has 6 plastic screws keeping panel door in place in front of panel. Use a flat

screwdriver to lose them and remove the panel door assembly. Please take care and remove

the connectors on the electronic card while removing the cover. Fix the panel on to the wall

via using 4 screw holes in each corner after removing the front cover. M4 screws are suitable

to fix the panel body to the wall. Once wall mounting completed reattached the front cover

and tighten 6 plastic screws.

To prepare cable entries, remove plastic cover from top or bottom on the panel. Then drill

the holes for cable entry and install cable glands to the holes you made it. Make sure you are

using an adequate IP66 rate cable gland to assure the box ingress protection is not

compromised. The panel box is modular and can be used with different assemblies. Prosense

recommends having cable entries from the lower side. Electronic board is located in the

front cover of the panel. The power supply is located at the back of panel box. The power

must be connected to this power supply. If the installation requires the connection to a

backup battery, place the battery to lover right side of the panel inside.

S-DP32 Panel has 32 LEDs numbered from1 to 32 nearby LCD panel. These LEDs will be

activated in case of an alarm to show which detector is raising the alarm. If any of these LEDs

are active it indicates the detector having that address has reached specified threshold level.

LCD Screen:

LCD screen shows time details and status of each detector connected to channels as shown

in Diagram 8. As The LCD screen can show 6 lines at same time there are up to six pages that

you can move via UP and DOWN buttons:

Table 4: LCD screen details

If there is no detector connected to channel, LCD screen will show it as FLT and fault LED will

be activated. That channel should be closed (deactivated) via using menu steps.

The LCD screen brilliance is adjustable by blue potentiometer shown in Diagram 9.

Fault Status:

Device is in fault state; all related fault text is shown on the display as a text.

The panel reports FAULT status in below cases:

•In case any of the detector connections lost

•In case any of the detector measurement level goes below minimum level

•In case any of the detector goes in to fault state

•In case any panel self-test result reports a fault

•In case panel main power lost and while panel is working with battery power

•In case panel main power supply fails

This status has been detected by panel when an input signal is below 3mA and reported on

LCD screen on related channel with “FLT” symbol. Panel will activate FAULT relay and LED in

case of any fault. Panel also activate fault LED for related channel if the fault status detected

on a detector channel.
