Blower Run Time Set with CM2 Motorized Teller Unit
The CM2 teller unit has a pressure switch that will act like a carrier arrival switch turning
off the turbine motors. The pressure switch should be activated after the carrier passes the
air relief valve in the teller bend turning off the turbines. The platform will remain closed
until the carrier lands and the pressure is equalized releasing the pressure switch. This
action is to ensure the platform does not open while the carrier is falling in the tube.
The “blower run time” is set using switch number one (SW1), which is located on the
control board in the customer unit. The unit is shipped with a default time stored of about 3
seconds. This procedure will overwrite any existing times set in system. This time can be
reset as often as necessary. Power failure will NOT affect the times stored.
Setting procedure for blower run time with CM2 Motorized Teller Unit.
1) Restore default times as described above.
2) Before beginning, the carrier must be in customer unit with customer door open.
3) Turn SW1 to the “ON” position. (LED indicator will light)
4) Push and hold the “Customer Send” button until carrier arrives in the teller unit. The
carrier will activate the carrier arrival switch, and the blowers will automatically
turn off.
5) Wait for the teller platform to drop open with the carrier. This will happen after the
carrier lands and pressure is equalized in the teller unit.
6) Push and hold the “Teller Call” button until carrier arrives in the clear acrylic tube
on the customer unit. Releasing the button stores the time held for this carrier travel
cycle. (Turbines will shut off when button is released, but the customer door will
stay closed)
7) After carrier lands in customer unit, press and release “Teller Call” button to open
the door. This stores a third time for carrier free fall time in the clear acrylic tubing.
8) Turn SW1 to the “Off” position for normal operation.
