Leckstar 5 relay for JOLA leak detectors

Description

The Leckstar 5 relay for JOLA leak detectors is designed for limit level signalling. They shall be installed in a control cabinet or other suitable protective enclosure. The switches are suitable for use in clean environments.

• without cable disconnection control and with switchable self-hold
• for connecting all conductive electrodes without a cable break control unit
• with 1 potential-free switching contact at the output Relay electrode for mounting or DIN rail mounting via 2 drill holes, with connection terminals at the top and 1 LED for alarm status indication.

The unit is designed to be mounted or installed in a switch box in a suitable protective enclosure and can therefore only be mounted/installed in these locations. It is only suitable for use in clean environments.

Self-hold:

• If the Self-hold switch is activated, an alarm is stored. The relay continues to signal the alarm even if the cause of the alarm (e.g. presence of water or cable break) is no longer present – in other words, if the sensor is dry again. The alarm is acknowledged by switching off the self-hold switch.
• If the self-hold switch is not switched on, the alarm will not be maintained when the cause of the alarm is eliminated, but will be interrupted.

Before use, we recommend viewing the attached pdf documents under the Documentation tab.
