For a single Piston Tank type EA (with AutoStop) or TA (with AutoTrim) switch unit UNI is adequate. The UNI already offers three fail safe devices such as low voltage and transmitter signal monitoring.
This unit is available with the low voltage monitor pre-adjusted for 6V and 12V operation (approx. 4V or 9V respectively). The low battery voltage is also adjustable by turning the potentiometer on the switch board.
For two Piston Tanks type EA or TA switch unit TAE is recommended. This unit offers transmitter signal monitoring and maximum depth control (via pressure switch 5028).
Switch units TAE2 and Tmax2 can be upgraded with a Static Depth Controller which allows the static (not moving) model to be held at a desired depth.
For Piston Tanks type XP a proportional switch unit is necessary.
Switch unit SBTS is sufficient when only a single tank is used. The SBTS has almost the same fail safe functions as the standard UNI but allows proportional Piston Tank control.
For two Piston Tanks Type XP switch unit Tmax becomes necessary. This system offers adaptive proportional and individual control as well as three fail safe functions.
The Tmax is available with the low voltage monitor pre-adjusted for 6V and 12V operation (approx. 4V or 9V respectively). Low battery voltage limits are also adjustable for individual setup of the system.
All switch units can be equipped with a pressure switch which limits maximum operational depth of the model to approx. 1.8 meters.
The pressure switch is included in switch units TAE, TAES and Tmax.
For switch units UNI and SBTS the pressure switch can be ordered separately (item no. 5028).
