.Power supply can be used in a wide range of 100 to
240 VAC. (Wide range voltage supply) The pumlp is
free from the power voltage fluctuation.
.Operation keys and LCD display offer high-precision
setup and a variety of control modes.
.Injection amount can be controlled and pump opera-
tion/stop can be controlled by input signals. An;alog
signals of 4-20 mA DC (0-20 mA DC is available in
the case of PZi8 model), pulse signals (flow meter
signal, open collector, etc.), or open collector si!gnal
can be used for controlling the injection amount.
.Contact signals such as a level switch can be il1put
directly as the operation/stop signal.

Refer to the "PZD Series Operation Manual."
.Manual operation:
The number of strokes (spm) can be set directly on
the operation panel.
(Set within the range 1 to 300 spm digitally in single-
step increments.)
.Automatic operation:
Control is performed by changing the number of
strokes per minute by external signals (analog signal,
pulse signal).
.Timer operation
The interval function is automatically turned ON/OFF
according to an internal timer.
(The PZi4 is not provided with this function.)
.Stop input signal control:
Pump operation is controlled by non-voltage contact
signals from a level switch or other device. (External
stops and control by alarms can be set.) (PZi4/8)

7-1 Manual mode
1. Basic operation
(1)The number of strokes can be set digitally in
single-step increments within the range 1 to 300
spm by the UP, DOWN key on the operation
panel.
(2)With the PZiB and special function models, the
display unit (spm) can be switched to % or
mUmin.
2. Purpose of use
.Test operation after pump installation
.Temporary operation, for example, when an error
occurs during automatic operation (e.g. signals
are not output)
.The stroke speed during automatic operation
(multiplication, count, interval) can be changed.

Check the installation state of the PZi, hoses on the
discharge and suction sides, and power supply and
signal lead connections. If there are no problems for
installation, turn the power ON.

Purpose of use
.This mode is used for flowrate proportional injec-
tion, etc. The pump operates proportionally to the
number of input pulses from the outside.
.Used when there is a large number of pulses
from a flow meter or other instrument, and thla
chemical infection amount is too great. (settirlg in
direction for reducing injection amount)

2. Purpose of use
.This mode is used for flowrate proportional injec-
tion, etc. The pump operates proportionally to the
number of input pulses from the outside.
.Used when there are a few number of pulses
from a flow meter or other instrument, and the
chemical injection amount is too small. (setting
in direction for increasing injection amount)
.Fine-adjustment of discharge volume is per-
formed by the stroke adjustment dial. (See 10.

7-4 Multiplication mode
1. Basic operation
(1) Pulse signals from the outside are received, and
automatic operation is performed by the number
of strokes corresponding to the multiplication.
(2) The multiplication can be set within the range 1
to 9999. At this time, the pump operates at the
number of operation strokes (spm) set in the
manual mode.
Multiplication (can be set within range 1 to 9999)
As the default setting, external signals are canceled when an
external pulse input signal is input again during pump opera-
tion. External pulse input si~nals can also be held and stored
to memory by setting in this mode. (PZi8 type special func-
tion model only)

1. Basic operation
(1) The start signal is received and the pump oper-
ates for the number of preset times. (batch pro-
cessing)
(2)The setting value can be set by a combination
of 1 to 9999 times and X1, X10, X100, X1000
multiplication. (1 to 9999, 10 to 99990,100 to
999900, 1000 to 9999000)
(3)Start signal can be selected from an external
input and START-STOP key.
(4)The end signal (100 msec one-shot signal) can
be output when operation for the preset count
ends.
2. Purpose of use
This mode is used in sites where fixed amounts are
repeatedly injected. Operation can be easily
instructed or confirmed from the outside by the
start and end signals, for example, during batch
injection to a container on a conveyor belt.

8 Setting Up Operation
8.1 Changing the Operation Mode
For PZi, the manual and automatic (pulse, analog, etc.)
control methods can be switched by changing the
operation mode. To change the operation mode, hold
down the MODE key for at least 0.5 seconds with the
pump stopped. This sets the pump to the setup mode.
If the MODE key is held dow~ longer, the screen
enters setup screen for each mode. Do not hold the
MODE key down longer when changing the operation
mode.
Remarks:
0 If the key is not pressed for five seconds at [Setting
state], the newly set value is canceled, and the STP
state is returned to.
0 In the [Setting state], the setting value blinks, and
lights by pressing the ..~ keys. The value is
scanned.
I:t
8-2
*1: The parameter setup screen is moved by pressing the key for three seconds with the SET key pressed only
during a manual pump stoppage.
*2: In the manual mode only, the setting value can be changed by pressing the'" ...keys during both a pump stop-
page and operation" and the setting value determined by pressing the SET key.
*3: The MODE key and the SET key are the same. To change the operation mode with pump operation stopped,
release the MODE key within 0.5 seconds. Holding the MODE key down for 0.5 seconds or longer sets the pump
to the setup mode. -7-
