Examine the instrument for possible shipping damages. IMPORTANT: If for any reason it is determined that the equipment should be returned to the factory, please notify the nearest Robertshaw Industrial Products sales representative prior to ship- ment. Each unit must be properly packaged to prevent damage. Robertshaw assumes no responsibility for equipment damaged in shipment due to improper packing. -

Page 10: Space Heater
909GF299 SPACE HEATER In some outdoor installations, it may be necessary to install a space heater to prevent moisture condensation. For Vibraswitches with a SPDT switch (Table 1, Designation A) a small conventional carbon 2 watt resistor should be installed across terminals 6 and 8 in the detector. Proper values are shown in Table 3-1. Space heat- ers cannot be readily installed in the field in Vibraswitches with a DPDT switch (Table 1, Designation D). -

909GF299 b. If the Model EURO 366G is to be mounted in unprotected or dusty areas, a dust-tight or water-tight seal should be made at the conduit entrance. c. With all mounting complete, remove cover and insert wires through conduit entrance with sufficient length to reach the terminal block. -

Page 13: Operation
909GF299 SECTION IV OPERATION OPERATION The Vibraswitch, Model EURO 366G (Refer to Figure 4-1), is sensitive to vibration in a direction (the sensitive axis) per- pendicular to its mounting base. It contains a vibration detecting mechanism, which also functions as a “mechanical am- plifier”, to activate a snap-action switch when the selected level of vibration is exceeded and the detecting mechanism “trips”. -
Page 14: Adjustment Of Operating Setpoint
It is agreed that this method can lead to differences in the classification of degree of vibration between individual ob- servers. It is Robertshaw’s contention, and experience bears out this conclusion, that if the machine is operating satisfac- torily as previously defined and the acceleration as measured by the Vibraswitch is within certain limits, the settings as outlined in the instructions will offer protection to the machine and prevent catastrophic failure. -
Page 15: Setpoint Adjustment
909GF299 Normal G-Level Measurement With the machine (equipment) operating, back off the Setpoint adjusting screw one turn CCW and reset. If it will not reset, back off the Setpoint adjusting screw two turns CCW, etc. Again turn the Setpoint adjusting screw slowly clockwise until actuation occurs. -

909GF299 SECTION V MAINTENANCE TROUBLESHOOTING Vibraswitches do not normally require any maintenance or repair, however, listed below are some of the possible mal- functions that may occur and their recommended solutions (Ref. Figure 4-1). Perform all tests with field wiring discon- nected. - Page 18 909GF299 c. Unable to Adjust Setpoint Setting to Obtain Tripping Improper air gap between Hold-down (lower) Magnet and Armature. Return the Vibraswitch to the factory for repair. d. Switch Does Not Actuate Defective or improperly adjusted switch - (Ref. Figure 4-1). Manually move the Armature between the hold down magnet (armed position) and latching magnet (latched position) and listen for an audible click of the switch.
