INTRODUCTION

The PROPLUS YPP7000 meter boasts specifications and functionality that clearly
makes it one of the most advanced temperature meters available. Its dual-line 6­character display, function keys, and optional expansion modules are only a few

of the features you will find on the PROPLUS.

A fully loaded YPP7000 meter has the following: four SPDT relays, 4-20 mA output,
and one 24 VDC power supply to power the 4-20 mA output. The YPP7000 capa­bilities may be enhanced by adding the following external expansion modules: four
SPST relays (creating an eight-relay temperature meter), two digital I/O modules
with four inputs and four outputs each, and USB, RS-232 or RS-485 communica­tion adapters.

The eight relays can be used for alarm indication or temperature control applica­tions. The 4-20 mA isolated output, Modbus RTU serial communications, and digital
I/O options make the YPP7000 an excellent addition to any system.

INSTALLATION

There is no need to remove the meter from its case to com­plete the installation, wiring, and setup.

Instructions are provided for setting up a 12/24 VDC powered
meter to operate from 12 VDC power, see page 16.

Unpacking

Remove the meter from box. Inspect the packaging and con­tents for damage. Report damages, if any, to the carrier.

If any part is missing or the meter malfunctions, please contact
your supplier or the factory for assistance.

Panel Mounting Instructions

 Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x

45 mm). Refer to Figure 1 below, for more details.

 Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.

 Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).

Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.

 Remove the two mounting brackets provided with the meter (back-off the two

screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the
bracket toward the front of the case and remove).

 Insert meter into the panel cutout.

 Install mounting brackets and tighten the screws against the panel. To

achieve a proper seal, tighten the mounting bracket screws evenly until me­ter is snug to the panel along its short side. DO NOT OVER TIGHTEN, as
the rear of the panel may be damaged.

Do not exceed voltage rating of the selected configuration.

Meters equipped with the 12/24 VDC power option are shipped
from the factory ready to operate from 24 VDC.

To configure the meter for 12 VDC power:

1. Remove all the connectors.

2. Unscrew the back cover.

3. Slide the back cover about 1 inch.

4. Configure the J9 jumper, located behind the power con­nector, for 12 V as shown below.

Thermocouple and RTD Connections

The following figures show examples for thermocouple and RTD con­nections.

The TYPE selector switch must be set to the proper position for the me­ter to accept the selected RTD or TC input.

The RANGE selector switch is used to select 100-ohm platinum or
10-ohm copper RTD. The 1000-ohm platinum RTD input uses the same
setting as the 100-ohm RTD.

The input type is selected using the Setup menu.
The selected thermocouple input must correspond to the thermocouple

sensor and wire type used.

The four-wire RTD connection is similar to the three-wire. One of the

The three-wire connection provides sufficient lead wire compensation to
obtain accurate readings even with long leads.

Modbus RTU Serial Communications

Serial communications connection is made to an RJ45 connector
labeled M-LINK on Figure 4. For interfacing to the PROPLUS use the

YPPA1232 for RS-232, the YPPA1485 for RS-485, or the
YPPA8008 for USB. The same port is used for interfacing with all
expansion modules (i.e. external relays, digital I/O).

Use the YPPA1200 meter copy cable for meter-to-meter interfacing for
cloning purposes (i.e. copying settings from one meter to other meters).

Relay Connections

Relay connections are made to two six-terminal connectors labeled
RELAY1 – RELAY4 on Figure 4. Each relay’s C terminal is common
only to the normally open (NO) and normally closed (NC) contacts of the
corresponding relay. The relays’ C terminals should not be confused
with the COM (common) terminal of the INPUT SIGNAL connector.

Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching
inductive loads to prevent disrupting the microprocessor’s operation. The sup­pressors also prolong the life of the relay contacts. Suppression can be obtained
with resistor-capacitor (RC) networks assembled by the user or purchased as
complete assemblies. Refer to the following circuits for RC network assembly
and installation:

C

C

R

R

Figure 12. AC and DC Loads Protection

Choose R and C as follows:
R: 0.5 to 1  for each volt across the contacts

C: 0.5 to 1 µF for each amp through closed contacts

Notes:

1. Use capacitors rated for 250 VAC.

2. RC networks may affect load release time of solenoid loads. Check to con­firm proper operation.

3. Install the RC network at the meter's relay screw terminals. An RC network
may also be installed across the load. Experiment for best results.

Use a diode with a reverse
breakdown voltage two to
three times the circuit vol­tage and forward current at
least as large as the load
current.

Note: Relays are de-rated to 1/14th HP (50 watts) with an inductive load.

External Relays & Digital I/O Connections

The relay and the digital I/O expansion modules YPPA1004 &
YPPA1044 are connected to the meter using a CAT5 cable provided
with each module. The two RJ45 connectors on the expansion modules
are identical and interchangeable; they are used to connect additional
modules to the system.

Note: The jumper located between the RJ45 connectors of the

YPPA1044 must be removed on the second digital I/O module
in order for the system to recognize it as module #2.

Do not connect or disconnect the expansion modules with
the power on!

Warning!

More detailed instructions are provided with each optional
expansion module.

Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more,
alarm/control relays for use as interlock relay(s). Interlock contact(s) are
wired to digital input(s) and trigger the interlock relay. This feature is
enabled by configuring the relay, and relative digital input(s) (see page

56). In one example, dry interlock contacts are connected in series to

one digital input which will be used to force on (energize) the assigned
interlock power relay when all interlock contacts are closed (safe). The
interlock relay front panel LED flashes when locked out. The interlock
relay would be wired in-series with the load (N/O contact). See below.

SETUP AND PROGRAMMING

The meter is factory calibrated prior to
shipment to read temperature in degrees
Fahrenheit. The calibration equipment is
certified to NIST standards.

Overview

There are two switches, located at the back of the meter, to set the input
selection for TC or RTD and for 100-ohm platinum or 10-ohm copper.
The 1000-ohm RTD input uses the same setting as the 100-ohm.

Setup and programming is done through the front panel buttons.
After power and input signal connections have been completed and

verified, apply power to the meter.
