Outputs
The eight output relays can be individually set to either normally
open or normally closed contacts using jumpers JU1 to JU8 on the
module circuit board. JU1 sets the polarity of output 1, JU2 sets the
polarity of output 2, etc. Each jumper can be set to NO (normally
open) or NC (normally closed).
Each pair of outputs - O1/O2, O3/O4, O5/O6 and O7/O8 - can be
linked so both relays are energised together when the first output of
the pair is activated. Jumpers JU9 to JU12 set this function.
JU9 in the O2-01 position links outputs O1 and O2.
JU10 in the O4-03 position links outputs O3 and O4.
JU11 in the O6-05 position links outputs O5 and O6.
JU12 in the O8-07 position links outputs O7 and O8.
With the jumpers in the IND position, the outputs function
separately.
Linking outputs enables two devices operating at different voltages to
be switched at the same time.
Also, by setting one of the linked outputs to be NO and the other to
be NC, the pair can be used as changeover contacts.
Installing the 4953 Status Display module
Note: this module can only be fitted to a 4253 Input/Output module
16/8.
1. If the 4253 I/O module is already installed in a Controller, you
must switch off the power and remove it from the Controller
before installing the Status Display module.
2. Make sure that you have the 4953 Status Display module the
correct way round so that the LEDs will be visible when the
4253 module is installed in the Controller.
3. Locate the three connectors on the Status Display module on
CONN8, CONN9 and CONN10 on the I/O module. Make sure
that all the pins are inside the connectors and none are
sticking out - it is possible to press the module on to the
connectors with some pins not engaging in the sockets.
4. Press the module on to the connectors and check again that all
the pins are engaged in the sockets.
5. Set up as described later.
6. Install the 4253 I/O module in the Controller.
