The SMX70 stop/jog economizer board is supplied with a motion detector to monitor the rotation of the energy recovery wheel. The sensor is a hall effect device that senses the passage of a small magnet on the perimeter of the rotor. When the sensor fails to register any wheel rotation - it requires a signal every 20 seconds or 10 minutes depending on the mode of operation - it energizes the alarm terminal (24 VAC, .3 amp max) of the SMX70 board.

Fan Bearings (Pro-75 and Pro-90 only) – The fan bearings for the Pro-75 and Pro-90 require lubrication at a regular interval. Hours of operation, temperature and surrounding conditions will affect the lubrication frequency required. Therefore, when applying grease, observe the condition of the grease expelled from the bearings and note the amount of grease used. Both observations will suggest whether or not the lubrication schedule should be increased or decreased.
Installation 1. Turn belt with tabs to the inside before installing. 2. Determine direction of drive rotation. 3. Align belt directional arrow with drive rotation. 4. Fit belt in nearest groove of smaller sheave. 5. Roll belt onto larger sheave, turning the drive slowly. Belt may seem very tight; this is okay. DO NOT jog motor. Pro-Series 6. Check to see all tabs are still in their correct position and are not twisted out of alignment. 7. For multiple belt drives, work belt from groove to groove.
