1. Introduction
The OriLink® TCM module, (
T
ank
C
ontrol
M
odule), is used to control pumps and/or measure levels in tanks using
floater based level switches. A TCM can be used both for fresh and waste oil tanks.
The TCM (23408) is eighter a MPDM (23400) with another software (early model the chip should be labeled TCM
1.xx.xx) or has the PCB 203 02 91 equipped with a chip marked TCM 2.xx.xx.. Because of this a lot of this manual is
similar to the manual of the MPDM.
NOTE!
The Orilink® installation manual should be available when installing and configuring a TCM.
2. Mechanical installation
The TCM is delivered mounted in a metal box with power supply. It can also be delivered as a PCB with mounting kit.
Complete TCM in a box is mounted on a wall or other suitable place using the four-ø5 mm holes in the bottom corners
of the box.
If a PCB is used it is important that a power supply with enough performance is used.
3. Electric installation
The power supply should be connected to mains
230VAC in a proper way following valid rules.
Alentec & Orion AB recommends that the
connection be done through a 2-pole working
switch.
It has five connectors
(A)
for the OriLink® communication. Two of these connectors,
MPDM IN
and
MPDM OUT
are not connected to
+24V
and are intended for a connection to another TCM, MPDM or other modules that already
have +24VDC. This is to prevent conn24VDC from two power supplies.
The other three connectors are used to connect external devices without a power source such as a Printer Module (PM),
a LED Module (LED) and/or a KeyPad (KP). These connectors can only supply power to a single device. For more
detailed information see the
OriLink® Manual
NOTE! If the communication loop begin in one of these modules it must be connected to either MPDM IN or
MPDM OUT or +24V must not be connected.
The RESET-button
(B)
can be used to reset the module or reset the module address. Power supply is connected to the
connector
(C)
.
NOTE!
Check polarity, GND is closest to the hole!
The connector
(D)
is used when you install a chassis-mounted key switch and diode.
With the key switch you can set the status of the module to OFF-, NORMAL-, or
OVERRIDE-mode. The diodes indicate setting.
There are four connectors
(E)
24 V, OC, A, B and GND, one for
each pump/tank. Solenoid valves and level sensors are connected to these
connectors.
“A” of a TCM port is connected to “order oil/emptying” of the level
sensor.
“B” of a TCM port is connected to “Stop level” of the level sensor.
“GND” of a TCM port is connected to common of the level sensor.
“+24V” of a TCM port is connected to one of the terminals of a solenoid
valve and “Sol” is connected to the other.
