NanoTron C/B units are designed to automate conductivity control and / or the addition of various chemicals or activate other devices via a relay output.
Nano-C and Nano-B2 units include:
– One totalizing water meter input that can be configured for contacting head or hall effect meter inputs.
– One drum level input that can be set to disable the feed relay output.
– Two mechanical relay outputs with normally open and normally closed contacts that can be configured for powered or dry contact relay operation (see page 4 diagram).
– A “force on” timer that allows for manual activation of the relays for a user defined amount of time.
Conductivity Control (C & B) – Conductivity monitoring and control of Total Dissolved Solids (TDS) in a recirculating water systems in terms of electrical conductivity measured in MicroSiemens/cm. The conductivity scale can be selected from three ranges (low, mid and high) in the Configure menu (see page 13 of the manual). One selectable feed timer is also included (see timer description below).
Feed Timer – One user selectable timer that can be individually programmed as one of the following types:
Pulse Timer – Accepts dry contact pulses from a water meter (supplied separately). It can accumulate 1-9999 pulses to activate the timer to run from 0-99 minutes, 59 seconds in minutes and seconds. Timer will store up to 5 additional activations during an individual run time.
Recycle Timer – Provides a user defined “off” cycle in HH:MM and a user defined “on” cycle in MM:SS that is repeated constantly.
28-Day Timer – 28-day feed timers, typically used for biocide feed are based on a 28-day cycle with two independent programmable feed cycles allowing for feed on selectable days and weeks.
Batch Timer – Timer activated by the Force On/Off key for a user defined run time.
Reminder Timer – Provides a 1-99 day cycle reminder alarm.
Post Bleed Timer – The relay is activated after a bleed cycle and runs for the set percentage of that bleed cycle.
With Bleed Timer – Activates the relay output simultaneously with the bleed and limits the amount of time the relay output will be on during the bleed cycle.
