3.3 Description
The GEMÜ 1235 electrical position indicator is suitable for installation on pneumatically operated linear actuators and, with spe-
cific mounting parts, likewise suitable for pneumatically operated quarter turn actuators as well as further selected actuator ver-
sions. The position of the valve spindle is reliably electronically detected and evaluated using play-free and non-positive mount-
ing. Intelligent microprocessor-controlled functions facilitate commissioning and support during operation. The current position
of the valve is displayed via high-visibility LEDs and fed back via electrical signals.
3.4 Function
The GEMÜ 1235 electrical position indicator shows the position of the valve. When the valve is opened, the spindle in the elec-
trical position indicator moves upwards and indicates that the valve is OPEN using the high visibility LEDs and communication
interface. When the valve is closed, the spring in the mounting kit pushes the spindle in the electrical position indicator down-
wards and indicates that the valve is CLOSED using the high visibility LEDs and communication interface.
