Warnings

See the Dyna-Star HP and HF Pump Instruction manual

for additional warnings.

Pressure Relief

Follow the Pressure Relief Procedure whenever

you see this symbol.

To relieve pressure in the system, use two wrenches

working in opposite directions on pump outlet fitting to

slowly loosen fitting only until fitting is loose and no

more lubricant or air is leaking from fitting. See FIG. 1.

Installing Low Level Indicator

1. Disconnect Dyna-Star pump from main power

source.

2. If unit has already been in service, relieve pressure

(see Pressure Relief procedure, page 2).

3. Fill reservoir with grease to raise follower plate (if

installed) to an easily accessible level.

NOTE:

• Installing the follower plate and low level will be

easier if the reservoir has been filled with

grease first.

• If a follower plate is not pre-installed, fill tank at

least half full.

4. Remove plug (a) from cover (b). Discard plug, you

will not reuse it (FIG. 2).

5. Loosen bolts (c) and remove cover (d) from

Dyna-Star pump (FIG. 3).

SKIN INJECTION HAZARD

High-pressure fluid from dispense device, hose leaks,

or ruptured components will pierce skin. This may look

like just a cut, but it is a serious injury that can result in

amputation. Get immediate surgical treatment.

Follow Pressure Relief Procedure in this manual,

when you stop dispensing and before cleaning, check-

ing, or servicing equipment.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury from

pressurized fluid, such as skin injection, splashing

fluid and moving parts, follow the Pressure Relief

Procedure when you stop dispensing and before

cleaning, checking, or servicing the equipment.

6. Remove screws (e) and washers (f) holding

Dyna-Star Pump to reservoir cover (b) and remove

pump from cover (FIG. 4).

7. Remove the screws (g) (holding the reservoir cover

(b) to the reservoir (h) (FIG. 5).

8. (If previously installed) remove follower plate from

inside reservoir.

9. Determine the correct cable length to use for your

pump reservoir.

• Short cable is used with 60# reservoirs.

• Long cable is used with 90# reservoirs.

Remove and discard the cable you are not using and the

Notice label attached to the cables.

10. For easy wiring, make sure the DIN connector is

facing out (FIG. 6). Feed the low level cable (j)

through accessory hole (aa) in the reservoir cover

(b). Wrench tighten low level in place.

FIG. 5

NOTICE

Failure to use the correct cable length could result in

inaccurate level indication and low level shutdown.

11. Remove one of the screws (k) from the follower

plate (m) (FIG. 7).

12. Install screw (k) through the hole (n) in the cable

bracket (p) located at the end of the low level cable

(j) and then through the screw hole (r) in the follower

plate (m) (FIG. 7). Tighten screw securely.

NOTE: Cable bracket (p) is slightly bent. Be sure to

install so the bracket will sit flat against the surface

of the follower plate.

13. Install follower plate (m) on top of grease inside res-

ervoir (h) with the cone side facing up. Press fol-

lower plate firmly into grease to remove all air

pockets.

14. Place reservoir cover (b) on top of reservoir (h).

NOTE: When reservoir cover (b) is correctly

installed on reservoir (h), the low level cable (j)

(installed between the low level indicator and fol-

lower plate (m) will be aligned in a straight and verti-

cal line as shown in FIG. 8.

15. Replace and tighten screws (g) securely (FIG. 9).

16. Slide pump down-tube through hole in the center of

the reservoir cover (b) and hole in the center of the

follower plate (m) as shown in FIG. 10.

NOTE: When pump is correctly installed, the breather (t)

will be below the control box (s) as shown in FIG. 11.

17. Replace screws (e) and washers (f) and wrench

tighten securely (FIG. 12).

18. Reinstall cover (d) using bolts (c) (FIG. 13). Use a

External Alarm or Warning Light (Optional)

An external (user supplied) alarm or warning light can

be added to the Low Level Indicator to provide an audi-

ble or visual signal in a low level situation.

1. Connect the DIN connector on the Low Level Indica-

tor to the (user supplied) alarm device. Connection

is made to PINS 1 and 3 of the DIN, Form “A” Field

Wireable Adapter. See FIG. 14.

2. Connect Dyna-Star pump to main power source.

3. Start system following pump start up procedure

included in the Dyna-Star HP or HF Pump Manual

provided with your system.

NOTICE

To avoid premature failure and the loss of fluid/low

level indication:

• Do not exceed the rating of the Low Level Sen-

sor Switch by connecting excessive lights or

audible signals.

• Level Sensor Switch is rated for a maximum of

32 VDC and 10 Watts. Maximum switch current

is 0.4 AMPS.

Low Level Visual Indication Sight Glass

332515F 7

Low Level Visual Indication Sight Glass

Normal Level Mark (FIG. 15) - Red rod is completely

covered by the green tube (G) and no red is visible in

sight glass. This appearance indicates that the lubrica-

tion supply container has sufficient material. No addi-

tional lubricant needs to be added.

Low Level Range (FIG. 16) - Red rod (R) is partially

covered by the green tube (G). Some red is partially vis-

ible at the top of the sight glass. This appearance indi-

cates that the lubrication supply container is

approaching the low level mark and needs to be refilled.

Low Level Mark (FIG. 17) - Red rod (R) is completely

visible with green tube (G) at lowest level. This appear-

ance indicates that the main lubrication supply container

is low and needs to be refilled.

For models equipped with a (user provided) external

alarm, when the fluid has reached this low level mark,

the sensor switch closes, activating the alarm.

reservoir (FIG. 18 and FIG. 19). Wrench tighten it in

place. 3. To determine the level of the fluid remaining in the

reservoir, loosen and remove dip stick (c) from res-

ervoir cover (b).

4. Use a clean rag to wipe oil/grease from end of dip

stick (c).

5. Insert dipstick (c) through hole (aa) in cover (b) as

far down as it will go and then remove it again. Visu-

ally inspect level of oil/grease remaining on dip stick.
