1 Scope of application
SUNSHINE centralized lubrication systems are designed to lubricate ball bearings, flat
bearings, flat slideways, circular slideways, linear guides, cams, gears, chains, etc..
SUNSHINE centralized lubrication systems are suitable for the lubrication of various
machines, such as lathes, mills, presses, planner, grinder, etc. It is fit to control different
lubricating points at the same time against different machines.
The YET lubrication units are suitable for using lubricant with a viscosity range at 30 to 250
cSt during it is running. Only new lubricant shall be used.
The design of YET series is to operate intermittently with an interval-controlled supply of
lubricant to the lubrication point. The interval time can be set from 1 to 999 per
second/minute/hour. The lubrication time can be set from 1 to 999 per second. The default
time unit of lubrication unit is second for lubrication and minute for intermittence. The user
can adjust time for lubrication quantity.
The maximum discharge rate of YET-K1 pump is 200 ml/min.
The maximum discharge rate of YET-K2 pump is 150 ml/min.
The max. discharge pressure for YET-K1 series is 7kgf/cm2, and YET-K2 series is
15kgf/cm2. The lubrication unit contains a pressure relief valve in order to prevent injury,
death, or property damage. YET-K2 model operates with piston type distributors and
through dump valve release pressure from the main line at the interval time.
For safety, a pressure switch should be mounted to monitor the system. The pressure
switch monitors whether the required pressure build-up occurs in the centralized lubrication
system during the pump cycle time and detects any leaking or lubrication connection
damage. The level switch is design to monitor the filling level and shut down the lubrication
unit when the lubricant is insufficient. To get further safety, the lubrication unit can connect
to other monitored device properly to enhance the alarm system.
Warning ! The maximum lubrication time is less than 2 minutes and the
minimum intermittent time is more than 3 minutes.

2 Basic operation
2-1 Safety information
2-1.1 Before installing
!Before installing, read the manual for the correct connection of the power. To prevent
chance of serious injury, death or property damage, disconnect the product from main
power supply before working on it.
!Comply with the specifications on the rating plate of the motor or the electrical
components..
!SUNSHINE centralized lubrication systems must not be used in other purposes other than
lubricating machines.
2-1.2 Before lubricant filling
You must observe the machinery manufacturer's information on the lubricants
to be used in the machinery.
!Use only new oil with a permitted range of oil viscosity from 30 to 250cSt. Warning !
Motor jammed or burned due to high resistance which caused by delivering higher than an
oil viscosity of 250cSt, no pressure build-up in centralized lubrication system or insufficient
oil delivery caused by pumping lower than an oil viscosity of 30cSt result in centralized
lubrication system failure.
! Only clean lubricant may be added. Please never fill with used oil.
!Never fill with chemical substances, water or hazardous fluids.
! All components of the lubrication line system - including reservoir, pipes, hoses, cut-off
valves, control valves, fittings, and so on - must be carefully cleaned before installation.
2-1.3 Control panel safety information
!In order to avoid disorders of the control panel, never let it have contact with water or oil.
2-1.4 Faults
! Only qualified, instructed specialists who are authorized by SUNSHINE may repair
lubricators and must use the original spare parts.

2-4 Installation
2-4.1 Positioning and mounting
(Fig.2)The lubrication unit is attached to the
intended mounting location (3) using appropriate
fastening materials (1).The mounting dimensions of
fixing holes for 2L are measured between 172 to
180mm ; 3L between 190 to 205mm ; 4L between
230 to 250mm. The installation location should be
spaced between 0.6m to 1.7m above the ground.
2-4.2 Filling Oil
Remove the oil tank cap and fill clean and
non-used oil into the tank and add up to the HIGH
mark (Fig. 3). Please note that only use permitted
range of oil viscosity between 30cSt to 250cSt.
Warning! Motor jammed or burned due to high
resistance which caused by delivering higher than an
oil viscosity of 250cSt.
Fig.3
2-4.3 Lubrication line connection
(See Fig. 4) Solder less tube connection (double
tapered sleeves) can be used. The tube (4) must go
through compressed bushing (1) and double tapered
sleeve (2). To avoid any leaking during running
service time, it should be observed up to
1mmdistance between the tube end to the double
sleeve. Insert tube end into counter bored port (3) up
to the stop. First tighten compressed bushing
finger-tight by hand. Then turn another 11/2 turns.

2-4.4 Wiring and alarm
Warning !! To prevent chance of serious injury, death or property damage,
disconnect the product from main power supply before working on it.
Install a fuse between the power supply and the product is strongly recommended!
The electrical circuit diagram of the lubrication unit is affixed inside the unit and can
be accessed by removing the cap.
Remove the cap (Fig.5) and inside you can see terminal plate and cable gland nut.
Loosen cable gland (Fig.6) and then insert cable through the cable gland hole (Fig.7) to
wire up. Fix the cable gland to the housing.
After electric connection is completed and then the power switched on, the level switch
would send a signal to the lubrication unit with alarm and alarm indicator light and the
motor stops at the same time when lubricant is insufficient. The user can connect terminal

point (remark NC/COM/NO) to other detectors or monitors for the application to stop
machine when the lubricant is insufficient.
After the electrical connection is finished, tighten the cable gland (Fig.9) and fix the
cover. Then turn on the power and the lubrication indicator light on the panel will lamp and
the motor feeds oil if the electrical connection is correct.

3-2 Intermittence Time/ Lubrication Time Display
The setting of intermittent time and lubrication time can be adjusted by pressing any
of or for two seconds and read from value from the display. If no
further action, the timer will restart after 5 seconds.
Intermittence time display indicates the set value and the remaining of intermittent time
during the lubrication unit working. Lubrication time display indicates the set value and the
remaining of intermittent time during the lubrication unit working. When pressing any of
the and of Lubrication Time/ Intermittence Time for two seconds,
the set-up value will be shown. If no further action, the timer will restart after 2 seconds.
3-3 Intermittence Time/ Lubrication Time set up
Press any of or for two seconds and then enter time setting
mode by pressing or to adjust time from 1 to 999 for interval and
lubricating. Continuously press or to fast increase or decrease value.
During time setting mode, two indicators will spark in the same time.
Time unit for intermittence is minute ; Time unit for lubrication is second
20 - 24
If no further action, the timer will restart after 5 seconds and run with new setting. The
lubrication indicator is light and intermittence indicator is dark during lubricating. On the
contrary, the intermittence indicator is light and lubrication indicator is dark at the interval.
3-4 RES button
Press RES button for two seconds, the lubrication unit will restart up and then run
default setting to deliver lubricant.
