MOFLASH SIGNALLING SB150-1 Series Manual

9.0 End of Line Monitoring
An End of Line monitoring Diode or an End of Line monitoring Resistor can be
connected across the 24V+ and 0 terminals. Resistor values for the End of Line will
be determined by the customer with a minimum value of 1.2kΩ
10.0 Maintenance
Little or no maintenance is required during the normal working life of the product.
The Moash Exd enclosures are resistant to most acids, alkalis and chemicals and
have been designed to withstand severe weather conditions. However it is suggested
that to avoid the possibility of a potential electrostatic charge build up, the exterior of
the product is periodically wiped down with a clean damp cloth. At this point a visual
inspection is recommended to ensure that the product is in good working order and
no damage has been sustained during its normal operation.

EN 60079-31:2009 (IEC 60079-31:2008)
8.0 Cable Gland
Only cable glands approved for Exd applications can be used with Moash
Explosion Proof Products, these must be suitable for the type of cable being used and
also meet the requirements of the Exd ameproof installation standard EN 60079-14.
SAFETY WARNING
If units are used at high ambient temperatures, i.e. over +400C then the cable entry
temperature may exceed +700C and therefore suitable heat resisting cable glands
must be used, with a rated service temperature of at least 950C.
If a high IP (Ingress Protection) rating is required, a suitable sealing washer must be
tted under the cable gland. Any unused cable entry holes must be closed with an
Exd ameproof blanking plug, which must be suitably approved for the installation
requirements.

5.0 Installation
General Requirement
The product must be installed in accordance with the latest EN60079-0 and
EN60079-1 specication or the equivalent IEC specication. Product installation
must be carried out in accordance with any local codes that may apply and should
only be carried out by a competent electrical engineer.
Location
The location of the unit should be chosen with due regard to the area over which
the beacon warning signal must be visible/audible. The unit should only be xed to
services that can support the weight of the unit.
Mounting
The warning signal can be mounted via the ‘U’ shaped stainless steel bracket. It
can be done using one 12mm diameter and two 8.5mm diameter bolt holes in the
center of the bracket (see diagram 1). The alignment and positions can be adjusted
by loosening the two M8 nuts which fasten the stainless steel bracket to the sounder.
The sounder should be positioned such that dust, debris or water cannot enter into
the horn opening.

6.0 Wiring
General Requirement
Moash recommends that all cables and cores should be fully identied (suggest
using cable from 2.0 to 2.5 mm²). Ensure that all nuts, bolts and screws are secured.
Ensure that only the right and certied cable glands are used and earthed correctly.
Ensure that only the right and certied stopping plugs are used to blank o unused
gland entry points. In order to maintain the IP rating of the product, we recommend
SS316 for this application.
Cable Connection
The supply cable is connected to terminals located on the Customer Terminal PCB
within the ameproof enclosure. The Sounder & Beacon PCBs are located on
the ameproof cover. Cable connection should be carried out in accordance with
relevant technical requirement.
Removal of End Cover
Unscrew the six (6) M5 retained hex socket head screws (see diagram 2). Twist
the cover gently clockwise and anti-clockwise, whilst pulling away from the body,
keeping the cover parallel to the body until it comes free. This will allow the cover
to hang on its retaining strap. Before replacing the cover, check that the ameproof
joints are clean and not damaged, the gasket is still retained in its groove.
Caution
Before removing the cover ensure the power to the sounder is isolated.
For AC units – connect Supply to Customer Terminal PCB marked ‘L& N’.
For DC units – connect Supply +to ‘L’ and ‘-‘ (0v) to ‘N’.
Alarm stages connect terminal S0 to S1, S2
(refer to table - section 7.0)
Do not connect Ac or Dc to terminals S0, S1, S2 & D
