Controllers

Installation Instructions

The following instructions are for

installing P-8000, T-5312,

T-8000, and T-8020 controllers.

Included are the instructions for

installing the accessory items.

Surface Mounting

Mounting of the P-8000, T-5312,

and T-8000 controllers may be

done on any type of surface

using #8 screws. It is

recommended that the surface

be smooth.

The T-8020 is designed for

direct mounting in the wall of a

tank, or in a pipe tee, using a

separable well. The separable

well is ordered separately to

facilitate installation, and has a

1/2 in. NPT.

External Adjustment

Knob Kit

The External Adjustment Knob

Kit (T-8000-17) consists of a

clear plastic knob and screw. To

assemble, remove the clear

plastic window from the lower

left of the cover. Insert the knob

through the cover and attach it

to the dial using the screw

provided. See Figure 2 for a

completed assembly.

External Pilot Orifice Kit The External Pilot Orifice Kit (T-8000-16) is designed for use when an 8000 series controller is required to operate if its input supply pressure drops below 5 psig (35 kPa) (the drop-off point of the relay). The following procedure should be used to install the kit: 1. Loosen capillary clip and rotate away from element. 2. Attach pilot air connection and insert pilot air line into hole provided in the back of the instrument. 3.

1. Note the ambient temperature or pressure at the element. Adjusting Instructions; Two-Position Instruments 2. Turn the dial post until the output pressure is in the middle of the spring range of the controlled device, if not already there. The two-position T-8000 has been factory adjusted to a differential of 4F° (2C°). The two-position P-8000 differential has been factory adjusted for 1 PSI (7 kPa) on the low pressure model, and 10 PSI (70 kPa) on the high pressure model.

3. Note the pressure or temperature settings on the dial. 4. Rotate the dial very slowly in the opposite direction and note when the switch point of the relay switches the output to the opposite value of that found in Step 1. 5. Note the reading on the dial. 6. The difference between the two dial readings is the exact differential.
