7.0 – DUAL PARAMETER DOSING PUMP AND PHRX CONTROLLER CTRL2
This unit is microcontroller based dosing pump includes both a dosing pumps and high tech controllers which
features three parameters all in one enclosure: PH or RX (ORP).
BENEFITS:
reducing stock value against a great quality and versatility
7.1 - CTRL2 DIGITAL CONTROLS
(fig.17)
1 - Enter button “OK”: confirms selection
2 - Increasing value button
3 - Decreasing values button
4 - "YELLOW" LED: level alarm / over dosing alarm / malfunction alarm
5 - "RED" LED injection pulse flashing
6 -

7.2 - CTRL2 CONTROLLER MAIN FEATURES
pH:
measuring range 0÷14,00 pH (resolution 0,01pH)
RX:
measuring range: -1000÷ +1400 mV (resolution 1mV)
•
2 Reset modes: full reset - partial reset keeping calibration settings
•
Proportional mode: selection of proportional range value
•
Delay adjustment - Delay at powering ON (electrodespolarization)
•
Stand-by for cleaning electrodesand sensors or re-calibration
7.3 - LEVEL CONTROL ONLY CTRL2/L
(fig.18)
The pump is supplied with level control setting and upon request floating level switch.
When the level of the additive is lower than the switch, level alarm and yellow led are
ON:
the pump is OFF
. The level control alarm goes ON within 5 seconds delay.
Floating Level Switch Joint level switch / filter
NOTE: when using a mixer in dosing tank this will cause turbulence, ensure that
floating switch is connected to filter fitting to avoid floating switch incorrect operations.
