8.1 DESCRIPTION
8.1.1 DC Timer. The DC timer is a solid-state, 12 to 32
VDC unit that energizes a DC solenoid when it is time to
start a lubrication cycle. The solenoid actuates the lubrica-
tion pump. The interval between cycles is adjustable from 1
to 10 minutes in eight steps. The duration of the lubrication
cycle is not adjustable and is 30 seconds long. The DC
Timer also features elapsed-time memory to ensure that
the interval between cycles is maintained during equipment
shutdown. A manual run button simplifies startup, testing,
and venting of lubrication lines and points. The manual run
button initiates one 30 second cycle each time it is de-
pressed. Refer to Paragraph 8.2.1 for installation instruc-
tions. Refer to bulletin 14511 for additional information.
8.1.2 AC Timer. The AC timer is a solid-state, 115/230
VAC, 50/60 Hz unit that energizes a solenoid valve when it is
time to start a lubrication cycle. The solenoid valve (See
Paragraph 8.1.1) activates the lubrication pump. The total
cycle time is adjustable from 0.5 minute to 32 hours. The
duration of the lubrication pump cycle is adjustable from 12
seconds to 13 minutes. The AC timer has a built-in memory
to keep the timer active for 1-1/2 hours during power failures
and machine shutdowns. This feature eliminates the
prelube cycle when power is reapplied after short shut-
downs. A manual run button simplifies startup, testing, and
bleeding of lubrication lines and points. When the manual
run button is depressed, it resets the system to the begin-
ning of the cycle and signals the pump to run for the
duration of the lubrication cycle. Refer to Paragraph 8.2.2 for
installation instructions. Refer to bulletin 14521 for addi-
tional information.
8.1.3 TC-1000 Timer/Counter. The TC-1000 Solid State
Timer/Counter is a microprocessor based multi-use
controller dedicated to the operation of centralized lubrica-
tion systems.
The TC-1000 schedules lube frequency either on a time or
stroke/cycle basis in values ranging from 1-9999. The
pump run interval is also selectable in time or counts over
the same range.
The TC-1000 is easily programmed in the field using four
mini push-buttons. No special training or knowledge of
computer language is necessary. During power down or
outage, data is saved in EEPROM (Electrically Erasable
Programmable Read Only Memory). When power is
restored, counting and pump status is restored to values
prior to loss of power.
Available for 115 VAC, 230 VAC, 12 VDC, or 24 VDC opera-
tion. Pump Output voltage is the same as supply voltage.
Refer to bulletin 14530 for additonal information.
8.1.4 WMP Maxi-Monitor. The WMP Maxi-Monitor is
designed to control and monitor a lubrication system and its
accessories. It can be used to schedule and monitor the
operation of lubrication pumps and divider valves in
automatic lubrication systems. The WMP is available in AC
or DC power source models.
8.1.4.1 The WMP Maxi-Monitor controls lubrication sched-
ules on either a time or a machine cycle/stroke count basis.
It will also continuously monitor and display the status of the
lubrication system it is controlling. It is capable of shutting
down a machine and lubrication system to protect it from a
loss of lubrication.
8.1.4.2 The WMP Maxi-Monitor is easily programmed. No
special training or knowledge of computer languages is
needed. Programming is done through a membrane
keypad located on the enclosure door.
Refer to bulletins 14750 and 14752 for additional
information.
