• Two totalizing water meter inputs that can be configured for contacting head or hall effect meter inputs.

• Two drum level inputs that can be set to disable the relay outputs.

• 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 of the manual).

• A “force on” timer that allows for manual activation of the relays for a user defined amount of time.

Each of the 2 timers in a NanoTron-F2 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.

Utility – Relay is on as long as it is not a flow or drum alarm.

After Timer 1 – This allows Timer 2 to run after Timer 1.
