Note:

In the drawings below for each input notice that the Slot A connector labeling is identified.

Note:

When using a 2 wire RTD, jumper S1 and T1 together

Inputs

All inputs shown below represent input 1 (the only input) and are to be connected to slot A of the PID

Control.

Process Volts and Amperes

• 4 to 20 mA @ 100 Ω input impedance

• 0 to 10VÎ (dc) @ 20 kΩ input impedance

• Scalable

Resistance Temperature Detector (RTD)

• Platinum, 100 Ω @ 0°C

• Calibration to DIN curve (0.00385 Ω/Ω/°C)

• 20 Ω total lead resistance

• RTD excitation current of 0.09 mA typical.

Each ohm of lead resistance may affect the

reading by 0.03°C.

• For 3-wire RTDs, the S1 lead must be con-

nected to R1.

• For best accuracy use a 3-wire RTD to com-

pensate for lead-length resistance. All three

lead wires must have the same resistance.

Thermocouple

• 2 KΩ maximum source resistance

• >20 MΩ input impedance

• 3 microampere open-sensor detection

• Thermocouples are polarity sensitive. The

negative lead must be connected to S1.

• To reduce errors, the extension wire for ther-

mocouples must be of the same alloy as the

thermocouple.

Power Supply Note:

Switched dc and Process outputs use a common power supply with a maximum current output of 40mA.

As an example, supplied current (mA) from output 1 and 2 can be 20/20, 30/10, 40/0, 10/30, etc...

Outputs

Please note all outputs are connected exclusively to slot A. Output availability is based on the part number

of your PID Control.

Quencharc Note:

Switching pilot duty inductive loads (relay coils, solenoids, etc.) with

the mechanical relay, solid state relay or open collector output op-

tions requires use of an R.C. suppressor.

Open Collector

• 100 mA maximum output current sink

• 30VÎ (dc) maximum supply voltage

• Any switched dc output can use the common

terminal.

• Use an external power supply to control a dc

load, with the load positive to the positive of

the power supply, the load negative to the

open collector and common to the power sup-

ply negative.

the value of the param-

eter in the lower display.

Zone Display:

When 2onE (found in the

Factory Page) is set to on, indi-

cates the controller zone.

1 to 9 = zones 1 to 9

A = zone 10 E = zone 14

b = zone 11 F = zone 15

C = zone 12 h = zone 16

d = zone 13

Lower Display:

Indicates the set point or output

power value during operation,

or the parameter whose value

appears in the upper display.

A/M Key:

This key will toggle the control

mode between the current value of

the C.M prompt (Off, MAn, AUto)

and Manual when the A/M button

is pushed and held for 3 seconds.

Infinity Key: ˆ

Clears and Silences alarms, press

to back up one level, or press and

hold for two seconds to return to

the Operations Menu.

Temperature Units Indicator

Lights:

Indicates whether the tempera-

ture is displayed in Fahrenheit

or Celsius.

Output Activity:

Number lights indicate activity of

outputs 1 and 2.

Percent Units Indicator:

Lights when the controller is

displaying values as a percentage

or when the open-loop set point

is displayed.

Communications Activity:

Flashes when another device

is communicating with this

controller.

Up and Down Keys: ¿ ¯

In the Operations Menu, adjusts the

set point in the lower display. In other

pages, changes the upper display to

An active message will cause the display to toggle

between the normal settings and the active mes-

sage in the upper or left display and [Attn] in the

lower or right display. Your response will depend

on the message and the controller settings. Some

messages, such as Tuning, indicate that a process

is underway. If a message is generated in the

right or lower display that can be cleared (such

as [AL;h1]), simply push the infinity ˆ key to

execute the action ([CLr]).
