Installation guide
Optimum functioning of the detector module is largely dependent on factors associated with the inductive sensor loop
it is connected to. These factors include choice of material, loop configuration and correct installation practice. A
successful inductive loop vehicle detection system can be achieved with 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 PD17x 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 PD17x Series parking detectors are rated to operate from -40°C to +80°C but the rate of temperature change MUST
not exceed 1°C per minute. 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.
