INSTALLATION GUIDE
Optimum functioning of the detector module is largely dependent on factors associated with the
inductive sensor loop connected to it. These factors include choice of material, loop configuration and
correct installation practice. A successful inductive loop vehicle detection system can be achieved
bearing the following constraints in mind, and strictly following the installation instructions. The detector
must be installed in a convenient weatherproof location as close as possible to the loop.
5.1 Product Safety Requirements
•
i) WARNING:
The unit must be GROUNDED (earthed).
•
ii) WARNING:
Disconnect the power before working on the unit.
•
iii) WARNING:
On 120 V
AC
and 230 V
AC
models a readily accessible disconnect device
must be incorporated into the mains wiring (as per EN60950-1:2005 Section
1.7.2.2).
•
iv) WARNING:
On all models the power supply to the unit MUST have short circuit protection
and over current protection installed at the power supply source (As per EN
60950-1:2005 section 1.7.2.3). Typically this will be a 5 Amp Magnetic Circuit
Breaker for AC models and a fuse for DC models.
•
v) WARNING:
This product must be installed in an enclosure as the IP rating of the detector
is IP 30.
•
vi) WARNING:
No user serviceable parts inside. No internal settings.
Warranty void if cover removed.
•
vii) WARNING:
Only use CE approved 11 pin relay bases such as Nortech Part No.
CTR119090 or equivalent.
As an alternative to the 11 pin relay base, Nortech has an 11 pin wiring
harness, Nortech Part No. 302FT0041, which can only be used in SELV
voltage (less than 60 V
DC
or less than 42 V
AC
) applications.
5.2 Operational Constraints
5.2.1 Environmental Factors to Consider
Even though the PD160 Enhanced Series parking detectors are housed, the system integrator MUST
ensure that the detector is installed in a housing/fire enclosure to protect it from the environment.
The PD160 Enhanced Series parking detectors are rated to operate from -30°C to +70°C but the rate
of temperature change MUST not exceed 1°C per minut e. This system integrator MUST ensure that
the housing used complies with this rate of temperature change requirement.
For installation Outdoors refer to Appendix B.
For additional information on Environmental Factors refer to the section “Environmental Influences
to Design Parameters” in the “Loops and Loop Installations” Manual, Nortech Document No. MKT05.
