4.0 3216CC Controller

message on the display and a flashing red ALM (Alarm) indicator. The alarm may also
switch an output – usually a relay to allow external devices to be operated when an
alarm occurs. Alarms only operate if they have been configured and are dependant on
customer requirements.

How to acknowledge an alarm will depend on the type of latching which has been
configured. A non-latched alarm will reset itself when the alarm condition is removed. A
latched alarm requires acknowledgement with the “ACK” Function (see section4.3.2)
before it is reset.

If an alarm has been activated the red “ALM” indicator will illuminate and the scrolling
text will indicate the type of alarm.

To Acknowledge an alarm and cancel the “ALM” indicator, press ACK function.

Note: The alarm indicator may seem to be permanently on when viewed from above.
When an alarm is active the indicator should only be flashing, to confirm this, the
controller must be viewed directly from the front.

Controller Options

As options can be ordered in a variety of combinations and for a variety of purposes,
exact instructions are not given here. The full Eurotherm manual may be required to
determine customer parameter settings. To reveal or hide parameters in the controllers
it is necessary to go into configuration mode, a security code is needed. Please consult
Carbolite Gero.

4.8.1

Digital Communications - RS232

If the RS232 option is supplied, the furnace is fitted with one sub-miniature D-socket
connected to the controller comms module. RS232 is suitable for direct connection
to a personal computer (PC) using a “straight through” cable as follows (the linked
pins at the computer end are recommended but may not be necessary). The cable
is usually 9-pin at the furnace end and 9-pin at the computer, but other alternatives
are shown in parentheses.
