 Verify that the audible alarm signal of the control unit can always be
heard, even in the case of ambient noise.
If audibility cannot be ensured, you must install an additional alarm unit at a
suitable location in the building (for example, additional alarm unit ZAG 01,
horn KH 1 or combined alarm light and horn from AFRISO).
5.1 Preparing mounting
Preparation also includes requirements concerning the interstitial
space and the leakage containment.
Information on these requirements can be found at the end of these
operating instructions.
5.2 Mounting the photoelectric probe
UNAVAILABLE MEASURING FUNCTION
• The probe is not intended to be permanently submerged in liquid.
Failure to follow these instructions can result in equipment damage.
 Verify that the probe is submerged even in the case of small amounts of
liquid.
 Verify that the tip of the probe is not subjected to mechanical load.
1. Mount the photoelectric probe at the lowest point of the area to be moni-
tored (lying or suspended).
- Do not suspend the probe directly from the control unit.
2. Use the holder supplied with the product or a cable clamp to provide strain
relief for fastening.
3. Place the probe at a position where there is little or no influencing light.
