Electrical Wiring.
NOTE - See figure 2b, section 1 for full wired diagram.
2.4.1
Connection to the mains electrical supply.
2.4.1.1 The manifold power is supplied by a mains power
cable, providing 24V DC for the electronic component. It
is not needed for the extra transformer.
2.4.1.2 The lead should be permanently connected to
an essential single-phase supply of 240V AC.
2.4.1.3 Ensure the electrical supply is isolated before
carrying out any mains connection.
2.4.1.4 Wire the lead into a 3 amp unswitched fused
spur.
2.4.1.5 Turn the power on and check that the LCD
screen on the front of the panel and screen is working.
2.4.1.6 Turn the power off.
2.4.2
Medical Gas Alarm Connection.
2.4.2.1 All internal control wiring such as solenoid and
sensors are completed during manufacture.
2.4.2.2 If remote alarms are used, run the 5-core alarm
cable to the power PCB (Item 30, Figure 1) through the
cable gland where shown in Figure 8.
NOTE - Typical alarm cable spec Alpha wire 117C 5 core,
maximum length of 100 m from alarm to manifold
control panel.
2.4.2.3 Connect the alarm cable to the terminals shown
in figure 8.
2.4.2.4 If a non BeaconMedaes remote alarm is to
be used, the output signal from the manifold can be
changed from the standard line contact resistors to a
closed in normal condition by following the set-up menu
detailed in Section 2.5.
2.4.3
For BMS connection route the cable and connect
as shown in figure 8.
2.4.4
When using as a backup manifold use alarm
outputs from "change cylinders" A10 & A11. Select
LMC output if connecting directly to a Medipoint alarm
system. Refer to section 2.6, figure 14 for how to set up.
