Celsius Scale Conversion
A Celsius scale throttling range decal is included with
the A350P control. If the Celsius scale is desired:
1. Locate the throttling range and minimum output
potentiometers on the main PC board.
(See Figure 2.) Carefully remove the knobs and
the existing decal.
2. Apply the Celsius scale decal in the same place as
the original decal.
3. Rotate both knob stems completely
counterclockwise (CCW).
4. Reinstall the potentiometer knobs so the arrows
point to the minimum values.
The A350P Temperature Control is housed in a
compact NEMA 1 plastic enclosure designed for
standard 35 mm DIN rail mounting. Four key-slot
mounting holes on the back of the control case are
provided should surface mounting be required. If a
Y350R is used, it should be mounted immediately to
the right of the control. Any S350 modules would
follow on the right, with the D350 being the last module
mounted, also on the right.
Note:
When mounting any System 350 module to
rigid conduit, attach the hub to the conduit
before securing the hub to the control
enclosure.
!
WARNING: Risk of Electrical Shock.
Disconnect the power supply before making
electrical connections. Contact with components
carrying hazardous voltage can cause electric shock
and may result in severe personal injury or death.
AVERTISSEMENT: Risque de décharge
électrique.
Débrancher l'alimentation avant de réaliser tout
branchement électrique. Tout contact avec des
composants conducteurs de tensions dangereuses
risque d'entraîner une décharge électrique et de
provoquer des blessures graves, voire mortelles.
