Temperature Controller

E5CS--X

A--150

Operation

J Settings Before Applying

Power

Note:

Always turn off the power supply to the temperature control-

ler before changing any switch settings.

Before applying power to the temperature controller, set the

following selector switches to specify the temperature range,

functions and alarm mode.

J Access to Internal Switches

and Selectors

Push the tab on the underside of the front panel as you draw out

the internal mechanism from the housing. The temperature range

selector, and the alarm mode selector must all be set. A

protection switch can also be set to protect settings. The

following diagrams show the locations of these switches on the

internal mechanism.

Temperature range selector switch

Select the desired temperature range by using the temperature

range selector switch (rotary DIP type). The other rotary DIP

switch is used to select one of eight alarm functions. Be sure the

set temperature and alarm values are within the new range.

Otherwise, the temperature controller automatically shifts these

values to the maximum or minimum of the newly-set temperature

range.

The protection switch may be used in conjunction with the front

panel “hidden key” to prevent unauthorized changes to

temperature settings. The switch is ON when it is pushed inwards

in the direction of the white arrow.

The function selector switch is a 8-pin in-line DIP switch on the

other side of the internal mechanism. Use it to select ON/OFF or

PID control action, proportional period, control output, input shift

function, temperature sensor input standard and scale indication

for dual-scale temperature ranges.

J When All Functions Have Been Selected

To Set Temperature

Press the return key until the SP indicator lights. Then set the

desired temperature value by using the Up and Down keys.

To Set Alarm Value

Press the return key until the AL indicator lights. Then set the

desired alarm value in units of

°For °C. If the present tempera-

ture exceeds the set alarm value, the alarm output will be issued.

Neither the set alarm value is displayed nor the AL indicator

lights with the integral alarm mode setting switch set to 0 or 9. Be

sure to check the alarm mode setting switch, located inside the

housing, for proper setting.

In Case of Sensor Failure

The error message “FFF” or “------” will appear on the main display

if the temperature sensor short-circuits or breaks.
