Any external components (like Zener diodes, etc.)
connected between sensor and input terminals may cause

Notes:
1.Do not run input wires with power cables.
2.For TC wiring use proper compensating cable (use
type J TC extension wire with type J TC
connections), preferably shielded.
3.Shielded cable should be grounded at one end only.
RTD Input
Figure 4
RTDInputWiring
Notes:
1.Do not run input wires together with power cables.
2.Observe the line resistance; a high line resistance
may cause measurement errors.
3.When shielded cable is used, it should be grounded
at one end only to avoid ground loop currents.
4.The resistance of the 3 wires must be the same.

Relay Outputs (continued)
The OUT 1 NO contact and the OUT 2 contact are
protected by varistor against inductive loads with
inductive components up to 0.5 A.
OUT 1 contact rating is 3A/250Vac resistive load.
OUT 2 contact rating is 1A/250Vac resistive load.
The number of operations is 1 x 105at specified rating.
Notes:
1.To avoid electric shock, connect power line at the
end of the wiring procedure.
2.For power connections use No 16 AWG or larger
wires rated for at last 75 °C.
3.Use copper conductors only.
4.Do not run input wires together with power cables.
Inductive Loads
Employing the following recommendations will help
avoid serious problems that may occur when relay outputs
are used with inductive loads.
High voltage transients may occur when switching
inductive loads. Through the internal contacts these
transients may introduce disturbances that can affect the
performance of the controller.
For all the outputs, the internal protection (varistor)
assures a correct protection up to 0.5 A of inductive
component.
The same problem may occur when a switch is used in
series with the internal contacts as shown in Figure 8.

The SSR Drive Output is a time proportioning output.
Logic Level 0:Vout < 0-5 Vdc
Logic Level 1:14V ±20% @ 17mA
+24V ±20% @ 1mA
Maximum = 17mA
Notes:
1.This output is not isolated. An external solid state
relay with 2600V isolation must be used to isolate
the controller output and power supply for CE
compliance. The Chromalox Series 4115, 7710,
4001, and 4003 meet these isolation requirements.
2.To determine Output #1 output type, check the tag
on your controller and compare it to the model
identification table on page ii.
Inductive Loads (continued)
Warnings:
When a relay output is used to drive an inductive
load, it is suggested that you connect an external
snubber network (RC) across the terminals using
Chromalox P/N 0149-01305.

Power Supply
100 to 240 Vac
or 24 Vac/Vdc
Notes:
1. Before connecting the power line, check that the
voltage is correct (see Model Identification, pg. ii).
2. For supply connections use 16 AWG or larger wires
rated for at least 75 °C.
3. Use copper conductors only.
4. Do not run input wires with power cables.
5. Polarity does not matter for 24 Vdc wiring.
6. The power supply input is NOT fuse protected.
Please provide external fusing.
When the fuse is damaged, it is advisable to verify the
power supply circuit. Return the controller to Chromalox
for test and verification.
7. Safety requirements for permanently connected
equipment:
• Include a switch or circuit-breaker in the
installation.
• Place the switch in close proximity to the
equipment and within easy reach of the
operator.
• Mark the switch as the disconnecting device for
the equipment.
Note:
A single switch or circuit-breaker can drive more
than one controller.
8. When the NEUTRAL line is present, connect it to
terminal 10.
9. To avoid shock and possible controller damage,
connect power last.

General Operation
There are two setup modes for the 1603:
• Configuration Mode
• Operator Mode
In general, the Configuration Mode is the initial setup of
the controller when first installed. Input type and alarm
setup are examples of Configuration Mode settings. The
Operator Mode includes settings that might be adjusted
frequently with daily control operations such as setpoints
and PID parameters.
Pushbutton Functionality
During Configuration Procedure
FUNC =Must be pressed to store the new value of a
selected parameter and increments to the
next parameter.
SMART= In configuration Mode, scrolls parameters
back (in reverse order) without storing the
new parameter value.
▲ = Increases the value of the selected parameter .
▼ = Decreases the value of the selected parameter.
Configuration Procedure
1. Remove the controller from its case.
2. Set the internal switch V2 (see Fig. 9) in open
condition.
3. Reinsert the controller in the case.
4. Switch the controller “ON”.
Note: If “CAL” indication is immediately displayed,
press the ▲pushbutton to return to the configuration
mode “CnF.”
5. Push the FUNC pushbutton. The lower display will
show the parameter alphanumeric and the upper
display will show the parameter value.
