4.5. Passwords Reset

Contact ProMinent Technical Department, at (412) 787 – 2484,

with the controller serial number to obtain a

reset password which resets all passwords to the factory defaults shown above.

Proof of controller ownership is understandably required.

ProMinent controllers have no backdoor or super user password.

If you forget the password, this is the only way to recover controller access.

5. Application Notes

5.1. Sensor Inputs & Control Outputs

The controller uses the letters ‘A’ thru ‘F’ to identify input sensors, like pH, ORP, and Temperature, Flow

Switch, Surge Tank Level, Recirculation water flow meter, and other Digital signals. The numbers 1 to 5

identify the three (3) AC power switching relays and two (2) DC outputs for enable, alarm or pump pulse

frequency use.

‘A’ to ‘C’ and ‘E’ to ‘F’ exist as terminal blocks where inputs are connected. Sensor input ‘D’ is ‘virtual’ and

used to calculate Ryznar’s and Langelier’s SI indexes.

Users can also change the default names of sensors, pumps and valves to more meaningful, site specific

names. For example, although you may name controller meter input “E” to “Flow Switch”, ‘E’ identifies

where the meter is connected and the letter “E” is used to represent the “Flow Switch” input in hardware

connections and data logging.

Most inputs may be used to control almost any output with some logical aquatic application exceptions.

Function

Notes

Sensor

Fixed pH sensor input Support for all ProMinent pH sensors.

All controllers have one pH sensor input.

Sensor

Fixed ORP sensor input Support for all ProMinent ORP sensors.

All controllers have one ORP sensor input.

Sensor

Temperature Support for the ProMinent SGT 10mV/K temperature

sensor.

Thermal compensation for the ‘A’ pH sensor.

Phantom or

Virtual Sensor D

Phantom sensor inputs

have no physical

connection and are used

for control and logging.

This is a calculated value for LSI/Ryznar’s scale and

corrosion indecies.

Sensor

Fixed digital input There are two digital inputs. Input E is always used as the

Sample flow switch.

Sensor

Fixed digital input Digital input ‘F’ can be configured as an additional flow

switch or interlock, remote enable/disable, float switch, or

square wave pulsing flow meter.

Relays

AC Line powered outputs

ON/OFF controls

Controller powered outputs switch 120 VAC pumps, valves

& solenoids ON/OFF. Log time ON. Relays are N.O. only.

Relays 2-5 are SPDT for motorized valves requiring power

OPEN & power CLOSE if needed. Outputs can alarm on

runtime per actuation and per day.

Relays 4 and 5

DC switching outputs

Pulsing or ON/OFF

controls

DC Alarm Contacts, remote enable, or Variable speed pulse

output feeds. Presets for popular ProMinent and other pump

ml/stroke and maximum rates.
