This value applies only to the lines used by a single message. For example, if

this message uses only lines 2 and 3, then only lines 2 and 3 will be cleared.

Lines 1 and 4 will remain unchanged.

Important: AutoClear will de-energize the alarm relay only if the message

which was cleared had energized the relay. A DL50 message

display must always be sent a message that de-energizes the

relay.

Select Yes to activate or No to deactivate.

Repeat message automatically

This attribute (also referred to as AutoRepeat) causes the display to repeat a

message continually as long as no other message is in the queue waiting to

run. This attribute only functions if the DL40 message display is operating in

the Message/Variable/Slave or Message/Variable Run Mode.

This attribute is useful when you need to update variables repeatedly within a

message.

Select Yes to activate or No to deactivate.

Chain message to another

With this attribute you can link two messages together so that the second

message will run automatically after the Wait Time for message has

expired. The second message requires no additional triggering and no special

modification of its attributes to respond. Also, the link is independent of the

second message, which means that the second message can also run

independently under other circumstances.

The second message will have its own attributes, which may be different

from those of the first message. There is no limit to the number of messages

that can be chained together, and messages can be chained to Special

Messages.

Note: The Chain message to another attribute will be disabled if

AutoRepeat is active.

Activate this attribute by entering a valid message number.

Energize relay

Activating this attribute will display the message and energize the DL40

message display’s alarm relay whenever the message is triggered.

Important: The alarm relay will not de-energize even after the Wait Time

for message has expired. The relay will de-energize when:

• a message is run for which the Energize relay attribute is

not activated

• any Special Message runs
