Control compartment
The signal cable of an external limiter (P/PI continuous
controller) is to be connected according to the wiring
diagram to the terminals "5" (Limit signal IN) and "7"
(Limit signal GND) of the control terminal block "XE2"
inside the control compartment .
The connecting cable must be led through a cable gland
into the control compartment.
Note: The limiter must be activated and configured
via the control software. The admissible limiter signal
values can be found in the technical data table in the
operation manual.

Control compartment
The optional remote operating and fault indication board
contains four potential-free relay contacts for the con-
nection of the following operating and fault indications:
– "Error" (Terminal 1 and 2):
This relay is activated if an error is present.
– "Service" (Terminal 4 and 5):
This relay is activated when the set maintenance
interval has elapsed.
Note: this relay can be configured in the control
software to close either when maintenance is re-
quired or when maintenance is required and when
a warning is indicated.
– "Steam" (Terminal 7 and 8):
This relay closes as soon as the Condair EL hu-
midifies.
– "Unit on" (Terminal 9 and 10):
This relay closes as soon as the voltage supply
to the Control compartment of the Condair EL is
switched on.
The connecting cable must be led through a cable gland
or grommet into the control compartment.
The
maximum contact loading
is
250V/8A
.
Appropriate suppressor modules are to be used for the
switching of relays and miniature contactors.
