TLR-50 Remote Controls are pressure-release
style systems which control the pressurization and
depressurization of the blast machine. Pressurization
occurs when the control handle is pressed and
depressurization occurs when the handle is released.
1.4 Operating
Principles
1.4.1
Clemco TLR Remote Controls operate
pneumatically on return air (Refer to Figure 1). If the
control handle lever (the main activator of the system) is in
the up (no blast) position, one stream of air travels down
the outbound side of the twinline and escapes through an
opening located under the lever. The normally-closed inlet
valve remains closed and the normally-open outlet valve
remains open. When the control handle lever is pressed,
a rubber button seals the opening, and air in the outbound
line returns through the inbound line to open the inlet
valve and close the outlet valve. This action pressurizes
the blast machine and begins the blasting process.
Releasing the handle exhausts the control air, closing the
inlet valve, and opening the outlet valve to depressurize
the blast machine and stop the blasting.
2.0 INITIAL
SET-UP
2.1 Factory-Installed
Controls:
If the remote
control has been factory installed, skip to Paragraph 2.3.
2.2 Field-Installed
Controls:
Refer to Figure 1.
WARNING
Failure to observe the following procedure
could cause serious injury or death from the
sudden release of compressed air.
Empty the blast machine of abrasive.
Depressurize the blast machine.
Lockout and tagout the compressed air
supply.
Bleed the air supply line and remove the air
line from the blast machine.
2.2.1
Remove the existing inlet valve and replace it
with the TLR-50 inlet valve. The directional arrow on the
valve points toward the blast machine, indicating the
direction of air flow.
