Technical data
Function
The function at a rise or drop in temperature appears from the figures 8 and 9. Permissible ambient temperature for thermostat housing. -40 – 65 °C (80 °C for max. 2 hours) Max. permissible bulb temperature “OIL” sensor on 060L113166: 150 °C. “HT” bulb: 250 °C Enclosure and tightness IP30 in accordance with EN 60529 / IEC 529. 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 AC; 16 FLA, 96 LRA
- 240 V AC; 8 FLA, 48 LRA
- 240 V DC; 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. NB: If other screws are used, make sure that they do not project more than 1.5 mm into the unit.

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.
Testing
Fig. 11
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 and 12
- “START” = starting temperature
- “STOP” = stop temperature
- “DIFF” = differential
Fig. 8 and 12
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. Locking the setting
Fig. 13 and 14
Both the “OIL” and the “HT” spindles can be locked with the locking plate. If sealing is required a sealing screw is used.
