Carbolite ABA 7/35B - Manual (Page 17)

17 MF60 – 1.04
5 ABA Operation
This section describes how to heat the chamber up to temperature, and how
the automatic door locking system operates.
5.1 Switches
– Control Panel
The main control switches are on the left hand side of the control panel (see Fig 5.1.1).
5.1.1 Fig - Mains switch panel
5.1.2 Fig - Electrical shock warning lights
The
‘furnace switch’ cuts off power to the
controllers, other devices (including the balance)
and heating circuit contactors.
The ‘safety circuit test switch’ is
used to check the operation of
the two red warning lamps
referred to in section 4.1 (see
Figs 5.1.1 and 5.1.2.)
The heater lamps indicate when the power control relays are on; they flash while the
chamber is heating or maintaining temperature. They are also used to diagnose faults – see
section 25.
5.2 Door Operation and Status Display
In previous models ‘door open’ and ‘door locked’ indicator lamps were positioned above the
‘Electric shock risk’ lamps on the upper right front of the furnace. These door status indicators
are now included (see Screen-views 4.4.1 and 5.5.1) in the status bar at the top of the
touchscreen display panel.
