4. Operation
TEC 2000 Installation & Operation Manual E2K-405-0902

Remote Momentary – Seal-ins activated
5. Momentarily pulse either OPEN or CLOSE control signal for 0.5 seconds minimum. The
actuator will move in the open or close direction to the end of travel.
6. Momentarily pulse the remote stop signal to stop the actuator movement:
Two-Wire Control
The two-wire control mode uses only one contact to control the valve. When the contact is
closed, the valve opens, and when the contact is open, the valve closes. Seal-in is not active
for Two-Wire control. The contact open and close status can be reversed in the “SETUP”
mode. See Section 5.6.4, Discrete Input Setup.
Three-Wire Control
The three-wire control mode uses two maintained contacts to open or close the valve. This is
an “inching” type mode. Remote seal-ins, “Momentary” mode, may be activated in the
“SETUP” mode. If the three-wire control is used with the seal-ins activated, the valve cannot
be stopped while being remotely controlled; the valve can only be stopped via the inhibit or
emergency stop inputs.
Four-Wire Control
The four-wire control mode uses three maintained contacts to open, close, or stop the valve.
The default configuration sets the stop input to be active on open contact. The default
configuration can be modified in the “SETUP” mode. See Section 5.6.4, Discrete Input
Setup.
Multi-Port Valve Control
The multi-port valve control mode allows remote control of a three-port valve with one inlet port
and two outlet ports or a four-port valve with one inlet and three outlet ports. Seal-ins,
“Momentary” mode is always active in this mode.
NOTE: Before operating in the REMOTE mode, the three port positions must be calibrated;
i.e. position limits set. See Section 5.6.3, Set Valve Travel Limits.
Multi-port valve synchronization calibrates the actuator to the correct switch position each
time the valve rotates through Port A position. An external contact or proximity switch must
be wired to source power input to terminals 5 and 8 for valve synchronization with reference to
valve Port A.
Local IrDA Port Control
The local IrDA port control mode allows the actuator to be controlled via the IrDA port. The
“Clicker” or any device such as a palmtop or laptop with an IrDA port may be used. The
“Clicker” or remote device will transmit STOP, OPEN, and CLOSE only.
NOTE: The setup mode cannot be entered via the IrDA port if this mode is selected in the
“SETUP” mode. ”SETUP” mode must be entered via the local control knobs and the control
mode must be changed to a control mode other than IrDA port before the IrDA port can be
used for setup.
Local RS-485 Port Control
The local RS-485 port control mode allows the actuator to be controlled via the RS-485 port.
Any device with a RS-485 port and application software to support the EIM proprietary
protocol can be used. The remote device is a slave to the CCM and has a slave address of 4.
The device can only return STOP, OPEN, CLOSE, and ESD commands. The device can be
connected to the same RS-485 link as the RDMs and used simultaneously with the RDMs.
