2216L and 2208L
Temperature Controllers
Installing and Operating Instructions
The 2216L and 2208L are precision PID temperature controllers
ideal for plastic extrusion machines, ovens, chillers and other
heating and cooling processes. The 2216L is in a 48 x 48mm panel
size (1/16 DIN) and the 2208L in a 48 x 96 panel size (1/8 DIN).
Both controllers have up to three outputs for heating, cooling and
alarms. In addition the 2208L has two contact closure inputs to
select second setpoint and standby mode (all outputs off, except
alarms).
The controller will have been built and configured according to
the ordering code given on page 5. Check the ordering code on
the controller side labels to determine the configuration of your
particular controller.
This controller meets the European directives on safety
and EMC.

To install the controller
Please read the safety information on pages 5 & 6 before
proceeding.
Prepare the panel cut-out to the size shown
Insert the controller through the cut-out.
Spring the panel retaining clips into place. Secure the
controller in position by holding it level and pushing both
retaining clips forward.
Unplugging the controller
The controller can be unplugged from its sleeve by easing the
latching ears outwards and pulling it forward out of the sleeve.
When plugging the controller back into its sleeve, ensure that
the latching ears click into place to maintain the IP65 sealing.
Wire Sizes
All electrical connections are made to the
screw terminals at the
rear
of the
controller. These accept wire sizes from
0.5 to 1.5 mm
2
(16 to 22 AWG), and are
protected by a hinged cover to prevent
hands or metal making accidental contact
with live wires. Rear terminal screws
should be tightened to a torque of 0.4 Nm
(3.5 lb in).
