Mounting:
Dismantle the safety guard over the electri-
cal cubicle of the Cooler. Loosen the oblong cable gasket
on the front of the electrical cubicle, just so much that the
quick connector of the communication cable can be inserted
through the opening. See Fig. 1.
A common cable can be used for both the signals. The ex-
isting cable glands can be used if the diameter of the cable
does not exceed 6.5 mm. If a thicker cable is used, wire it th-
rough any of the lead-throughs to the side of the cable gland.

Start signal free normally-open contacts for cooling,
on/off
Connect to terminal blocks 45 and 46.
0-10 V control signal for regulating the cooling capacity
The control signal must not exceed 10 V +10 %.
Connect to terminal blocks 47 (−) and 48 (+).
important!
Both signal inputs must be connected.
type A and B group alarms
Priority A group alarms are indicated on a closure of the potential-
free relay contacts between terminals 9 and 10.
Priority A group alarms are indicated on a closure of the potential-
free relay contacts between terminals 11 and 1.
in-operation indication
Indication that the pumps are in operation can be
obtained by an alternating potential free relay contact. Terminal
block 15(NC), 16(Com) and 17(NO).
A common cable may be used for all signals. The existing cable
gasket may be used if the cable diameter does not exceed 6.5
mm. If a thicker cable is used, it will have to be run through one
of the cable glands to the side of the cable gasket.
installation in the GolD, version C.
Run the cable(es) into the electrical cubicle via the cable gland, or
via lead-throughs on the backside of the top panel hood.
Start signal
Connect to terminal numbers 7 and 8.
0-10 V control signal
Connect to terminal numbers 4 (-) and 43 (+).
group alarm A and possibly group alarm B
Connect alarms from the Cooler to the External Alarm 1 or the
External Alarm terminals. The alarm in the Cooler is factory-
preset with priority A, which means that only group alarm A
normally needs to be connected. Connect the conductors from
terminals 9 and 10 in the Cooler controller to terminal numbers
50 and 51, or 5 and 53, in the GOLD control unit.
in-operation indications
There is no external operation input in the GOLD unit.

instructions for the Cooler with 0-10 v Controller
General
The Cooler is supplied with two optional accessories for
controlling the cooling load. Extra interference protection
is required for the Cooler variants for which the cooling
load is controlled by an external 0 –10 V DC signal.
To comply with the provisions of the EMC Directive that
deals with insensitivity to interference, analogue inputs
must be protected by a Ferrite block, 019 10.
Communication cable 019 007 is the accessory that must
be used if the Cooler operates together with the GOLD
ventilation unit, Version B. See individual instructions on
this topic.
Design
Ferrite block, 019 10 is designed to snap on around ca-
bles. The block consists of two ferrite halves that rest in a
plastic casing that can be opened. The plastic casing has
”hinges” and a simple lock that simplifies opening and
closing it around relevant conductors.
Dimensions: H= 15 mm, W= 15 mm, L= 9 mm and diame-
ter of openings = 6.6 mm
installation
After installing the relevant cables for operating and con-
trolling the Cooler, fit the ferrite block.
Fit the ferrite block around the conductors connected to
terminals 47 – 48 (0-10 V control signal) and the conduc-
tors on terminals 43 – 44 (steady 10V output signal), if
used.
Position the ferrite block as near as possible to terminals
47 – 48.
