  • Page 35: Cable

    For a multi-drop application, where the measuring supply is fixed to 4 mA, the voltage on the terminals of the Pointek CLS500 should be at least 12 V. The loop circuit is completely isolated from the measurement circuit. It is designed so that the internal capacitance and inductance on the terminals are isolated, and are not a factor in safety calculations.

    With three devices, at 3 x 68 nF, the allowable cable length will be considerably limited. Notes: • If the device is part of a multi-drop setup, Pointek CLS500 sets the current to 4 mA, which inhibits analog signalling, including fault signalling. •...

    Free Programming Mode Pointek CLS500 is most often used in FailSafe High or FailSafe Low mode (with linked alarm and fault signalling functions) selected at menu 1E. However, Free Programming Mode is an alternative. In Free Programming Mode all menu items operate independently, and continuous level measurement, with a mA signal proportional to level, is available.
