Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

Connect to Auxiliary Fittings

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splash ing fluid and moving parts, follow the Pressure Relief

Procedure when you stop dispensing and before cleaning, checking, or servicing the equipment.

Disconnect and isolate all power supplies.

Relieve pressure in the system using two wrenches working in opposite directions on the pump element and pump element fitting to slowly loosen fitting only until the fitting is loose and no lubricant or air is leaking from fitting.

NOTE: When loosening the pump element fitting, do not loosen the pump element. Loosening the pump ele ment changes the output volume.

NOTICE

Do not attach unsupported equipment to auxiliary fit tings such as fill ports and pump element. Attaching unsupported equipment to these fittings can result in irreparable housing damage.

• Always use two wrenches working in opposite directions when connecting anything to pump ele ment or auxiliary fittings. See F IG . 15 for an exam ple.

• Torque pump element fittings to 50 in-lb (5.6 N•m).

• Torque pump element to 65 in-lb (7.3 N•m) when connecting to the housing.

Pressure Relief Valves

F IG . 15

To prevent over-pressurization, which can result in equipment rupture and serious injury, a pressure relief valve appropriate for the lubrication system must be installed close to each pump outlet to allevi ate unintended pressure rises in the system and pro tect the pump from damage.

• Only use a pressure relief valve that is rated for no more than the working pressure of any com ponent installed in the system.

• Install a pressure relief valve before any auxiliary fitting.

NOTE: A pressure relief valve may be purchased from

Graco. See

Pressure Relief Valves , page 15.

NOTE: A spacer is required for operation. Only one

Graco spacer can be used at a time. The pumps from the factory have a spacer (25N814) installed on the pump element.

Pump Element Kits (page 30) come

with a spacer. The spacer may be replaced depending upon the required output volume.

4. Re-install the pump element into the pump base, ensuring that the first thread of the element engages correctly.

NOTE: It may be necessary to repeat the pump outlet volume setup procedure after the pump is operating to adjust the volume of the dispensed fluids.

5. Use a wrench and tighten the pump element fitting.

Torque to 50 in-lb (5.6 N•m).

NOTE:

• The dispensed volume amount varies depending upon external conditions, such as lubricant temperature and back pressure from downstream connections.

• Use the volume adjustment process in conjunction with setting the ON time of the pump to control the output volume.

• The volume adjustment process should be used as a starting point for dispensing the desired lubrication volume.

Load Grease

To ensure optimal performance from the pump:

• Use only NLGI #000 - #2 greases appropriate for the application, automatic dispensing, and the equipment’s operating temperature. Consult with the machine and lubrication manufacturers for details.

• Fill the reservoir using a hand operated pump, pneumatic pump or electric transfer pump.

• Do not overfill.

• Do not operate the pump without having a reservoir attached.

NOTICE

• Always clean fitting (E) with a clean dry cloth prior to filling the reservoir. Dirt and/or debris can damage pump and/or lubrication system.

• Use care when filling the reservoir using a pneumatic or electric transfer pump to avoid pressurizing and breaking the reservoir.

Most alerts/alarms occur during ON TIME MODE.

However, if a Low-Level alert triggers near the end of an

ON TIME cycle, the alert will display while the controller is in OFF TIME MODE. A soft ware error occurring when the controller is operating in the OFF TIME MODE will also activate the alarm LED.

UP and DOWN ARROWS

• Hold both the UP and

DOWN arrow buttons together for 3 seconds to enter SETUP MODE.

• In SETUP MODE, the UP and DOWN arrows increase or decrease time and cycle setting values shown on the display.

• In RUN TIME MODE, pressing the UP arrow/CANCEL button terminates the lubrication period.

Controller Operation

The controller operates in two modes; RUN MODE and

SETUP MODE. Each mode has multiple functions.

RUN MODE

RUN MODE performs two functions while monitoring

Alert/Alarm conditions: ON TIME and OFF TIME.

• In ON TIME the motor is running and the lubrication is delivered. ON TIME can be configured to be active for a period of time in minutes or a period of lube cycles (cycle or proximity switch is required).

• In OFF TIME the motor is not running. This is a period where no lubrication is deliv ered. OFF TIME can be con figured for 15 / 30 / 45 min. or 1 to 99 hours.

By default, units with controllers are set to operate with an ON TIME period of five (5) minutes and an OFF TIME period of one (1) hour.

Once an ON TIME lubrication period begins, it can be terminated by press ing the UP arrow/CANCEL button.

While in RUN MODE the controller monitors Alert/Alarm conditions. See

Alerts and Alarms

Alerts and Alarms

The controller monitors and displays two types of events: Alerts and Alarms.

Alerts

Alerts do not cause the lubrication cycle to stop. These events are automatically cleared based upon the alert received.

An amber LED illumi nates under ALARM on the display when an

Alert occurs. See

Alert and Alarm Scenarios on page 27 for a description of

Alerts that could occur.

Alarms

Alarms cause the lubrication cycle to stop. Alarms can trigger immediately or can be the result of an escalated

Alert. Alarms must be cleared immediately.

A red LED illuminates under ALARM on the display when an Alarm

occurs. See the Alert and Alarm Scenarios table on page 27 for a descrip

tion of Alarms that could occur.

When an Alarm is triggered, any active lubrication cycle will be terminated. The display begins to count up to identify how long the Alarm condition has been present.

The counter begins in minutes, then changes to hours, with a limit of 99 hours.

See ADVANCED PROGRAMMING , page 23 for addi

tional information about configuring the controller for

Alerts and Alarms.
