Technical data
Function
The function at a rise or drop in temperature
appears from figs. 8 and 9.
Permissible ambient temperature for thermostat
housing.
–40 to +65°C (+80°C for max. 2 hours)
Max. permissible bulb temperature
"OIL" sensor on 060L1131: 150°C;
on 060L1132: 100°C.
"HT" bulb: 250°C
Enclosure and tightness
IP 44 in accordance with IEC 144 and DIN
40050. This grade of enclosure is obtained
when the unit is fitted on a flat panel or on a
bracket. The bracket must be placed in such a
way that all open holes are covered.
Contact load
See the scale of the unit.
Application in accordance with UL-requirements:
120 V a.c.: 16 FLA, 96 LRA
240 V a.c.: 8 FLA, 48 LRA
240 V d.c.: 12 W pilot duty
Mounting
The two bulbs are to be placed as shown on fig.
3, 4 and 6.
Fig. 2
2 types of mounting brackets with screws and
washers. To be ordered separately.
4 extra screws (M4 ´ 5) and washers can be
supplied against code number 060-1054.
NB: If other screws are used, make sure that
they do not project more than 1.5 mm into
the unit.

Fig. 10
Cable entry of plastic supplied. Can be used for
6-14 mm cable.
Fig. 11
Pg 13.5 screwed cable connection with special
nut to be ordered separately. Can be used for
6-14 mm cable.
For 8-16 mm cable a standard Pg 16 screwed
cable connection can be used.

To be ordered separately.
Testing
Fig. 13
The main arm (3) is tilted.
When testing, the "RESET" knobs must be
activated simultaneously with the tilting of the
main arm (3).
NB. Use only the testing method shown.
Setting
Fig. 8, 9 and 14
"START" = starting temperature
"STOP" = stop temperature
"DIFF" = differential
Units with max./max. reset (060L1131)
Fig. 8 and 14
The highest oil and high-pressure gas
temperatures are set on the "OIL" and "HT"
scales respectively.
The "OIL" differential is fixed at 14°C.
The "HT" differential is fixed at 25°C.
The plant is restarted after stop by depressing
the "RESET" buttons. Restart cannot take place
until the temperature has dropped by a value
equal to the difference in question.
Units with aut./max. reset (060L1132)
Fig. 9 and 14
The lowest oil temperature is set on the "OIL"
scale.
The highest high-pressure gas temperature is
set on the "HT" scale.
The "OIL" differential is fixed at 12°C.
The "HT" differential is fixed at 25°C.
If the oil temperature is too low the compressor
stops and the heating element Q in the crankcase
is cut in. Restart is automatic when the
temperature has risen 12°C above the set value.
If the high-pressure gas temperature is too high
the compressor stops. Restart is carried out as
described under "Fig. 8 and 14".
Locking the setting
Fig. 15 and 16
Both the "OIL" and the "HT" spindle can be
locked with the locking plate. If sealing is required
a sealing screw is used.
