E-Stop Safety Modules with Fixed Delay –
Cancel Delay Input
The Cancel Delay Time input Y1-Y2 must be open during normal operation. After
the E-stop button is activated (its contacts opened), and the delay time is running, a
momentary closing of input Y1-Y2 will immediately terminate the delay time and open
contacts 37-38 and 47-48, and close contact 61-62. A jumper between Y1-Y2 results in
a Fault condition.
External Device Monitoring Settings
1-Channel Monitoring
If 1-channel monitoring is selected (see Figure 6), one or more normally closed
contacts from the MSCs must be wired to terminals X3-X4. If more than one contact is
used, they must be wired in series (see Figure 2). The second channel (X5-X6) must be
jumpered. The Module will reset only if both inputs are closed. After the unit is reset,
the state of the X3-X4 input is irrelevant.
2-Channel Monitoring
If 2-channel monitoring is selected (see Figure 6), the Module will check both inputs
X3-X4 and X5-X6 for closed state, before a reset can occur. After the unit is reset, and
during RUN mode, both inputs will be checked for matching state. In other words, if
one input opens, the other input must open within 200 milliseconds.
If both pairs of output contacts (both immediate and delayed) are used, and MSCs from
all four contacts are controlled (Figure 2), both an immediate MSC and a delayed MSC
contact must be connected in series to each of the two feedback inputs (Figure 2).
No External Monitoring
If monitoring contacts are not required or if External Device Monitoring is not otherwise
possible, jumper both X3-X4 and X5-X6 inputs and select 2-channel monitoring. It is
the responsibility of the user to ensure that any single failure will not result in a
hazardous condition and will prevent a successive machine cycle.

CAUTION . . .
!
Turn OFF Power Before
Removing Cover
The front cover should only
be removed and the switches set when
no voltage is applied to terminals A1-A2.
Changing the position of the switches
while power is ON could result in a
Fault condition or a short circuit.
