ON/OFF inputs
EH-105 has seven digital inputs that can receive contact information about AH
unit operation. (e.g., information about what state the AH unit is in when it is
running or On/Off alarm information). Contact information can also be connected
to NTC and transmitter measurement channels that have not been connected;
they are taken into use for this purpose here.
The symbol indicates which control the contact information is connected to.

AH start after

After acknowl.
The AH unit starts up 5 min. after the alarm has
disappeared without it being separately acknowledged.
Attention! Make sure that the pipe work is short enough so
it has time to warm up after a 5 minute delay and there is no
freezing risk, See p. 47.
You can label a general alarm. Directions for
using the text editor are outlined on page 6.
Note! The factory setting for the Emerg.Stop-
information is AH start after acknowledgement.
