Product Description

TCS9 Series Time Controlled Tank Level Switch

The TCS9 Time Controlled Level Switch is designed for use with tank level control applications such as the filling or emptying of a tank that is being controlled by a float or level switch. It provides scheduled level controll to fill or drain a tank to a pre-set level within a specified time window. It has daily and weekly timing options and can be programmed down to the minute. It can control pumps, solenoids and motorised valves.

Ideal for use with water and liquid storage tanks, chemical storage and dispensing, diesel tanks, bowsers, tankers and other uses.

It has a waterproof front cover (IP65) with LCD display and push button programming.

It is useful for sites where limited water pressure or pipe size require restricted operation of high flows at times of peak demand or where noise restrictions disallow the operating of pumps or valves at night. The TCS9 controller can also be used to restrict the availability of a switch controlled pump or valve where access to pumping should be limited to business operating hours such as tanker filling, etc.

A 20 Amp switching capacity allows the connection of larger appliances than a normal float switch, and without the voltage loss associated with long lengths of cable to a float switch, allowing the float switch to be extended to very long distances without loss of performance at the connected appliance.

In addition to the programmable timer function a manual over-ride setting allows operation to be enabled or disabled manually, so the unit can be set to always operate or never operate regardless of the programmed timer settings.

In the event of a power outage, timer settings will be retained for up to 200 hours by an on-board rechargeable battery integrated into the timer module. Time of day will also update as normal so there is no resetting or re-programming required and no loss of time normally associated with mechanical timers.
