Codes

Sensor Input Code

0 = Thermocouple

2 = RTD

Example

Model 4000-B-E-05C = a controller with a thermocouple sensor input; and SPDT relay output (non plug-in)

for setpoint I; a full scale process alarm for setpoint II; and a thermocouple J input range of 0 to 500°C.

*Not available on 4200

Troubleshooting

Before you call, please look at this section to see if your question is covered here. If you do call for technical

assistance, be ready to supply the following information:

NOTE: Fuse blowing

•

is not caused by the

•

controller. Blown fuses

•

are caused by shorts

•

in the heater circuit,

and must be corrected

to prevent damage to

the controller.

Symptom.

light, no digital display.

Probable Cause.

- No line voltage input

- Open PC board to back- plate connector

(defective connector)

- Open power transformer

Symptom.

reads ambient

Probable Cause.

- External backplate jumper missing (all

models except "S" and "F")

- Defective relay

- Open heater or heater circuit wiring

Setpoint I

Output type (Plug-In) Code

B = SPDT Relay, 7 A/5 A

F = 4-20 mAdc

S = Pulsed 20 Vdc

T = SPST SS Relay, 1 A

L = Limit Control*

Setpoint II Alarms

B = High deviation alarm only*

C = Low deviation alarm only*

D = High and low deviation alarm*

E = Full scale process alarm*

Athena's ZC/PC solid state contactors, Series 19 and 39 SCR

power controllers, can be added to boost ac load switching

capacity.

Check -

Verify 120/240 Vac, 50/60 Hz input voltage. Check

heater for shorts. Look for open breakers or open external

fuse. Remove input power. Check continuity through power

transformer primary. With ohmmeter, read between pins: 8

and 9 for 225 or 450 ohms +/-10% and 8 and 10 for 680 or

1000 ohms +/-10%

Corrective Action

- Replace heater, if shorted

- Restore power

- Replace either power transformer or backplate connector

Check -

If no readings in either step above, remove controller

from housing and repeat resistance measurements as above,

but directly on PC board lands corresponding to pins 8, 9, and

10. Correct readings indicate open PC board to backplate

connector problem. Incorrect readings indicate power

transformer problems.

Visually inspect relay contacts. Heater continuity and wiring

Corrective Action

- Install jumper

- Replace relay if contacts are worn or dirty

- Replace open heater, correct defective wiring
