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.

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.

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.

Relay Operation Details

Overview

The relay capabilities of the meter expand its usefulness beyond simple
indication to provide users with alarm and control functions. These ca­pabilities include front panel alarm status LEDs as well as either 2 or 4
optional internal relays and/or 4 external relays expansion module. Typ­ical applications include high or low temperature alarms, control applica­tions such as simple on/off temperature control. There are four basic
ways the relays can be used:

1. High or Low Alarms with Latching or Non-Latching Relays

2. Simple On/Off Control with 100% Adjustable Deadband

3. Sampling (Based on Time)

4. Relay Alternation Control

Relays Auto Initialization

When power is applied to the meter, the front panel LEDs and alarm
relays will reflect the state of the input to the meter. The following table
indicates how the alarm LEDs and relays will react on power-up based
on the set and reset points:

Alarm # HI or LO

1 HI 1000 500 499 Off

Front Panel LEDs

The LEDs on the front panel provide status indication for the following:

LED Status LED Status

1 Alarm 1 5 Alarm 5
2 Alarm 2 6 Alarm 6
3 Alarm 3 7 Alarm 7
4 Alarm 4 8 Alarm 8

The meter is supplied with four alarm points that include front panel
LEDs to indicate alarm conditions. This standard feature is particularly
useful for alarm applications that require visual-only indication. The
LEDs are controlled by the set and reset points programmed by the
user. When the display reaches a set point for a high or low alarm, the
corresponding alarm LED will turn on. When the display returns to the
reset point the LED will go off. The front panel LEDs respond differently
for latching and non-latching relays.

For non-latching relays, the LED is always off during normal condition
and always on during alarm condition, regardless of the state of the
relay (e.g. Relay acknowledged after alarm condition).

For latching relays, the alarm LEDs reflect the status of the relays, re­gardless of the alarm condition. The following tables illustrate how the
alarm LEDs function in relation to the relays and the acknowledge but­ton (Default: F3 key assigned to ACK):

Latching and Non-Latching Relay Operation

The relays can be set up for latching (manual reset) or non-latching
(automatic reset) operation.

Relay terminology for following tables
Terminology Relay Condition

On Alarm (Tripped)
Off Normal (Reset)

Ack Acknowledged

The On and Off terminology does not refer to the status of the relay’s
coil, which depends on the fail-safe mode selected.

In latching relay mode, latched relays will reset (unlatch)
when power is cycled.

Condition LED Relay

Normal Off Off
Alarm On On
Ack (No effect) On On
Normal Off Off

In this application, the meter is set up for automatic reset (non-latching
relay). Acknowledging the alarm while it is still present has no effect on
either the LED or the relay. When the alarm finally goes away, the relay
automatically resets and the LED also goes off.

Non-Latching Relay (A-nman)

Automatic + manual reset at any time

Condition LED Relay

Normal Off Off

In this application, the meter is set up for automatic and manual reset at
any time (non-latching relay). The LED and the relay automatically reset
when the meter returns to the normal condition.
The next time an alarm occurs, the operator acknowledges the alarm
manually while the alarm condition still exists. This causes the relay to
reset, but the LED stays on until the meter returns to the normal condi­tion.

Latching Relay (LatcH)

Manual reset any time

Condition LED Relay

Normal Off Off

Ack (No effect) On On
Normal On On

Ack Off Off
In this application, the meter is set up for manual reset only after the
signal passes the reset point (alarm condition has cleared). Acknowl­edging the alarm while it is still present has no effect on either the LED
or the relay. When the alarm is acknowledged after it returns to the
normal state, the LED and the relay go off. Notice that the LED remains
on, even after the meter returns to the normal condition. This is be­cause, for latching relays, the alarm LED reflects the status of the relay,
regardless of the alarm condition.

Acknowledging Relays

There are two ways to acknowledge relays programmed for manual
reset: via the programmable front panel function keys F1-F3 (Default:
F3 assigned to ACK) and remotely via a normally open pushbutton con­nected across one of the digital inputs and the +5 V terminals on the
digital I/O modules (Default: DI-4 assigned to ACK). When the ACK
button or the assigned digital input is closed, all relays programmed for
manual reset are acknowledged.

 The meter is factory calibrated prior to shipment to read

temperature in degrees Fahrenheit. The calibration
equipment is certified to NIST standards.

 There is no need to calibrate the meter, simply select

the input type, °F or °C, and decimal point.

 Check calibration of the meter at least every 12 months.

Allow at least 30 minutes warm-up time before performing recalibration
procedure to ensure specified accuracy.

63

Recalibration Procedure

1. Connect signal to the meter using the appropriate wire (e.g. type J

thermocouple wire to recalibrate type J input), see page 19.

2. Set up the meter to accept the selected input (e.g. type J T/C), see

page 36.

3. Set up the meter to display temperature in degrees Fahrenheit.

4. Apply signal corresponding to input 1 (32°F) and program the dis-

play to read 32.0.

5. Apply signal corresponding to input 2 (1184°F for type J) and pro-

gram the display accordingly.

6. After the meter accepts input 2, the display returns to reading

mode. This completes the recalibration procedure for the selected
input.

Noise Filter (filter)

The noise filter is available for unusually noisy signals that cause an
unstable process variable display. The noise filter averages the input
signal over a certain period. The filter level determines the length of time
over which the signal is averaged. The filter level can be set between 2
and 199. The higher the filter level, the longer the averaging time and so
the longer it takes the display to settle to its final value. Setting the filter
level to zero disables the filter function.

Noise Filter Bypass (bypass)

The noise filter bypass changes the behavior of the meter so that small
variations in the signal are filtered out but large abrupt changes in the
input signal are displayed immediately. The bypass value determines
the minimum amount of signal change to be displayed immediately. All
signal changes smaller than the bypass value are filtered or averaged
by the meter. The noise filter bypass may be set between 0.1 and

99.9% of full scale.

METER OPERATION

The meter is capable of accepting a variety of thermocouples and
RTDs.

The dual-line display can be customized by the user to operate in such
a way as to satisfy a specific application. Typically the main display is
used for the process variable; while the second display is used engi­neering units, custom legend, or set point indication.

Additionally the meter can be set up to display the thermocouple or RTD
input on the main display and the Modbus input on the second display.
The relays and analog output can be programmed to operate from the
Modbus PV input.
